The (recoil) energy spectra can be used to construct depth profiles of H and D concentrations within the samples. In elastic recoil detection (ERD) one determines the yield and energy of particles ejected out of the surface region of samples under MeV ion bombardment. And why not detect the energy of the secondary particle? Sketch of experimental geometry commonly used in ERDA experiments. Thin film samples were prepared in radio frequency plasma discharge of methane by varying the negative self-bias. (a). Orlando Auciello, in Ultananocrystalline Diamond (Second Edition), 2012. Then, the resistivity decreases as hydrogen percentage further increases. The authors therefore concluded that during CVD growth of GaN at temperatures above 800 °C, the liberation of surface hydrides can be ruled out as the rate-limiting step. (1996) reported surface studies of n-type GaN {000-1}-(1 × 1) surfaces grown by MOCVD, using time-of-flight scattering and recoiling spectrometry, low-energy electron diffraction, and thermal decomposition mass spectrometry. Inset: A quasi-linear relationship between the electrical conductivity of UNCD films (Y axis) and their bulk hydrogen concentrations (X axis). The (111) and (0001) faces of the two materials oxidized at the same rates. Elastic Recoil Detection Analysis (ERDA): ERDA is the measurement of recoiling atoms following elastic nuclear collisions at a glancing angle. [110] performed a systematic investigation of the oxidation kinetics of highly textured chemically vapor deposited silicon carbide films. Depth Resolution Kinematic Factor Grid Electrode Elastic Recoil Detection Analysis Stop Detector These keywords were added by machine and not by the authors. It is observed that, as hydrogen percentage in the gas feedstock increases, the resistivity of UNCD thin films firstly decreases slightly, and then increases more than two orders of magnitude from 3% to 6% hydrogen concentration in the plasma during the deposition process. Some N—H species decompose at 500 °C, and hydrogen eventually all desorbs at 600 °C. [49] using impedance and DC measurements on metal–diamond–metal capacitor test structures. For the analysis, an Oxford Instruments X-max 50 mm2 SSD Detector with INCA 350 Analyzer was used. A schematic of a forward recoil time of flight system is shown in Fig. Abstract We present a novel ion beam analysis technique combining Rutherford forward scattering and elastic recoil detection (RFSERD) and demonstrate its ability to increase efficiency in determining stoichiometry in ultrathin (5-50 nm) films as compared to Rutherford backscattering. The start and stop timing mirrors are usually thin carbon foils (5–30 μg/cm2), which generate a secondary electron timing signal detected by a set of microchannel plates. -type GaN {000-1}-(1 × 1) surfaces grown by MOCVD, using time-of-flight scattering and recoiling spectrometry, low-energy electron diffraction, and thermal decomposition mass spectrometry. A high concentration of hydrogen was also found below the surface, within a depth of 5–10 monolayers from the surface. The oxide that formed on the slow oxidation (111)/(0001) faces was optically different from that grown on opposite faces or on similarly oxidized samples of single crystalline silicon. (a). Academic & Science » Electronics. Elastic Recoil Detection Analysis (ERDA) When a MeV He ion beam incident on a sample with H and D, the H and D in the sample will be scattered in the forward direction. Copyright © 2021 Elsevier B.V. or its licensors or contributors. The overall timing resolution of the mirror system is typically less than 350 ps. R.W. The composition of the layers and their hydrogen content have been determined by Rutherford backscattering spectrometry and the, Science and Technology of Ultrananocrystalline Diamond (UNCD™) Film-Based MEMS and NEMS Devices and Systems, Ultananocrystalline Diamond (Second Edition), using impedance and DC measurements on metal–diamond–metal capacitor test structures. G.W. For testing the long-term performance of the coatings in acidic solutions, the pH was decreased to 2 with HCl. Elastic Recoil Detection Analysis (ERDA), also referred to as forward recoil scattering (or, contextually, spectrometry), is an ion beam analysis technique in materials science to obtain elemental concentration depth profiles in thin films. For better understanding of the effect of hydrogen concentration in the UNCD film on its electrical conductivity behavior, Figure 12.5 is re-plotted in Figure 12.6 as curve (B) and compared with curve (A) (bulk hydrogen concentration in a UNCD thin film as a function of hydrogen concentration in the plasma during film growth). We use cookies to help provide and enhance our service and tailor content and ads. ERDA is related to RBS, but in this case what is measured is the energy of the recoiling target nucleus. So, in RBS we are detecting the energy loss of the primary particle. 4 for a thin TiO2 layer on silicon. IBA techniques are useful when not only the composition of the samples, but also their depth profiles are determined in the first few micrometres. It is used principally as a method for measuring hydrogen in thin layers, and in the near-surface region of materials. Figure 12.5. (1995) also observed that H/D exchange can occur rapidly during NH3 exposure, even at room temperature. SIMNRA simulation of ERDA data 1.5 MeV 4He beam, 71° incidence, for a dPS/hPS/dPS (50 nm/100 nm/50 nm) trilayer film on a silicon substrate, illustrating the effect of differing range foil thickness. By application of this surface and thin film analysis technique one can obtain quantitative information concerning the depth distribution of light elements in a sample to be analysed. Handbook of Surfaces and Interfaces of Materials, ]. Thereafter, the EIS measurement was performed at OCP in the frequency range of 105 and 10− 2 Hz with a 10 mV exciting signal. (B) Re-plot of Figure 12.5 in linear scale by taking a reciprocal of resistivity data. Time-Of-Flight (TOF) was applied to ion separation and depth profiling in ERDA in systems that usually consist of two time detectors and a conventional silicon detector for the measurement of the energy. Elastic recoil detection analysis (ERDA) with an absorber foil using a 4.2 MeV 7 Li 2+ beam was utilized for evaluation of hydrogen depth profiles. The combination of PIXE/RBS offers a primary analysis technique complementary to SR-XRF and finds many applications in materials science. Apart from various conclusions about the surface structure, they found that hydrogen atoms were bound to the outermost layer of ν atoms, protruding outward from the surface with a coverage of three-fourths monolayer. Some of the background noise in ERDA experiments has been attributed to hydrogen from the range foil itself being ejected by the forward scattered beam from the sample. Smith, in Encyclopedia of Analytical Science (Third Edition), 2019. Yu et al. The solution was 0.2 M NaCl at pH 7.2 ± 0.2. Elastic recoil detection is one of the few techniques that can quantify hydrogen depth distributions in virtually any material. This process is experimental and the keywords may be updated as the learning algorithm improves. It can detect all the elements including hydrogen, and modern instruments have isotopic resolution. Figure 8.7. The ToF-ERDA measurements were carried out with a 1.7 MV Pelletron accelerator using 5.0 MeV 35Cl and 9.9 MeV 35Cl ions [1–5]. Schematic of the recoil time of flight target and detection system. Elastic Recoil Detection is a nuclear technique in materials science to obtain elemental concentration depth profiles in thin films. They found that hydrogen is released from Ga sites at temperatures between 250 and 450 °C. Spectrometry of these forward recoiled atoms gives rise to the quantitative depth profiling of these species in the sample. 123 Case Circle Although it is not easy to find micron-thick foils that are smooth and pinhole- and defect-free, replacing the polymer range foil with one that has negligible hydrogen may reduce the background noise by an order of magnitude.23 If it is necessary to improve the signal-to-noise ratio (e.g., for detecting trace quantities of 1H or 2H), then it is beneficial to switch to a hydrogen-free range foil. This along with the use of a TOF detector improves the depth resolution but the equipment required is expensive and complicated. Elastic recoil detection analysis (ERDA) was used to measure the H contents of 18 synthetic Fo 90 olivines that had been hydrated to varying degrees in high pressure hydrothermal experiments. (1996) investigated the effect of intentional introduction of atomic hydrogen during MBE growth of GaN. Used in combination with advanced data processing methods to combine the data, these methods can provide a complete internally consistent elemental analysis of a sample. The sample thinning for TEM consisted of the following steps: cutting the samples, embedding into a Ti-holder, mechanically grinding and polishing, milling with 10 keV Ar+ ions, and finally, milling with 3 keV Ar+ ions. In elastic recoil detection (ERD) one determines the yield and energy of particles ejected out of the surface region of samples under MeV ion bombardment. The curves reflect the parabolic relation between kinetic energy and velocity (Figure 8.7) from which the depth profile can be reconstructed. The recoil time of flight (ToF) spectrum is plotted against the energy spectrum producing a “boomerang” for each element from which the depth profiles can be obtained (Tirira et al., 1996). Composition of selected samples was studied with time-of-flight elastic recoil detection analysis (ToF-ERDA) and ToF-SIMS. Light elements (with mass < substrate) cannot be quantified in low concentration, and hydrogen determinations are impossible. The cross-section was prepared by focused ion beam (i.e., FIB) milling. The testing was conducted according to the standard DIN 50021 (ISO 9227) with the exception that the samples were removed from the testing chamber for photographing after regular intervals [1–5]. After H2 plasma cleaning the native silicon dioxide layer was partially removed, and the bias nucleation resulted in a mixture of SiO2 and SiC. The lab is also very active in multidisciplinary research, including fundamental ion solid interactions, accelerator based ion beam mixing, ion beam assisted film deposition, ion doping, Rutherford backscattering spectrometry, elastic recoil detection analysis, nuclear reaction analysis, and particle induced X-ray emission analysis. The spectrum can then be used to determine a depth profile of the H and D in the samples. They also suggested that the presence of hydrogen during GaN growth is an important factor in the growth of material with high crystalline quality: H atoms can maintain sp3 hybridization of the evolving surface, resulting in less ionic character. An RF plasma source was used for nitrogen, and atomic hydrogen was produced with a thermal cracker. 580-657-2575, Copyright 2020-2021 Amethyst Analytical | All Rights Reserved, Rutherford backscattering spectrometry (RBS), Particle Induced X-ray Emission (PIXE) spectroscopy, Other Available Characterization and Processing Tools. H, D, Li) from the sample are scattered in forward directions and can be detected with a Si detector. The ERDA technique provides a unique method for measuring the H and D content in thin films with detection limit ≥0.01 atomic %. [109] determined the complex dielectic function for diamond-like amorphous carbon layers and for amorphous carbon thin films (a-C:H) by spectroscopic ellipsometry. So, if you remember the kinematic scheme from RBS, we have two particles — the impinging one and the target particle. The working principle is shown in Figure 8.6. By continuing you agree to the use of cookies. As well as an energy-detection system, two timing mirrors are used to obtain a time of flight spectrum that is combined with the energy spectrum to form a two-dimensional plot (Martin et al., 1994). The composition of the layers and their hydrogen content have been determined by Rutherford backscattering spectrometry and the elastic recoil detection technique. Figure 7. Because of the relatively small energy loss of H in solids, the depth resolution of this method is typically ∼30–60 nm. This article outlines the ways in which MeV ions interact with atoms and solids and explains and illustrates how these interactions are used for analysis. ERDA is the complementary technique to RBS and is used mainly for profiles of very light ions such as hydrogen or deuterium in … If OCP and EIS measurements were done, they always preceded the more destructive LSV measurement. When the hydrogen concentration in the gas mixture is below 2%, the microstructure of deposited diamond film is dominated by nanocrystalline grains. The spectrometry of these forward-recoiled atoms generates the quantitative depth profiling of these species in the sample. Ramberg et al. RBS with helium ions is best suited for heavy element analysis on a light element substrate. The energy of the recoiling atoms is analyzed by a surface barrier detector to create a spectrum of the recoil atoms as shown in Fig. ERDA complements RBS in measuring light elements in matrices of medium or high average atomic number. Thompson, in Polymer Science: A Comprehensive Reference, 2012. (These materials are routinely incorporated into electronics and display equipment for which the tolerances and dimensional stability requirements are extremely stringent.) ERDA is also called Elastic Recoil Detection (ERD), Elastic Recoil Scattering (ERS) or Forward Recoil Spectrometry (FRS). Energy dispersive X-ray spectrometry (EDS) was used for elemental mapping of the cross-section of a defect site. A typical TOF-ERDA set-up is described by Norarat et al. The electrochemical responses of all uncoated and coated, low-alloy steel samples were studied with LSV [1–5]. The pressure was 10− 7 Pa. Ion Spec software was used for the data acquisition and post-processing analysis. Close correlations were observed between the hydrogen content in two types of diamond (MCD and UNCD) films, measured by, Journal of Electroanalytical Chemistry and Interfacial Electrochemistry. R.L. sensitivity of Elastic recoil detection analysis (ERDA) is increased at smaller recoil angles and it is advantageous to select M 1 ˛M 2. These names are listed below. In this way, ERDA data are collected for each raster point on the surface. From: Polymer Science: A Comprehensive Reference, 2012, Freddy Adams, Carlo Barbante, in Comprehensive Analytical Chemistry, 2015. The sample to be analyzed is irradiated with an ion beam (e.g. (A) Bulk hydrogen concentrations in a UNCD thin film as a function of hydrogen concentration in the plasma during film growth. # Elastic Recoil Detection (ERD) # Particle Induced X-ray Emission (PIXE) # RBS Ion Channeling (RBS-C) Ion Beam Modification # Ion Implantation # Radiation Effects # Ion Beam Mixing # Ion Beam Annealing # Ion Beam Track Etch. ERDA outperforms in certain respects the NRA technique (see below) in the case of hydrogen analysis. The films were prepared by microwave plasma CVD on crystalline silicon. Like other IBA methods, RBS/ERD can also be combined with a microbeam. The most pronounced changes in optical constants and in bonding structure occur near 500-V self bias. Atoms that are lighter than the incident ion recoil with higher energy than that of forward scattered ions are therefore easier to detect. The velocity of particles with the same energy but different masses will be different. By application of this surface and thin film analysis technique one can obtain quantitative information concerning the depth distribution of light elements in a sample to be analysed. Micro-Elastic Recoil Detection Analysis Micro-Elastic Recoil Detection Analysis (µERDA) is based on the same principles as ERDA. For RBS and PIXE the minimum beam current requirement is of the order of 100 pA. David D. Cohen, ... Rainer Siegele, in Encyclopedia of Physical Science and Technology (Third Edition), 2003. In this technique, an incident ion beam is directed at a grazing angle onto the sample's surface. This ambiguity can be avoided by using TOF-ERD. There are usually some orders of magnitude more forward scattered incident ions than recoiling nuclei, and these must be eliminated from the spectrum. The technique provides a quantitative elemental depth profile; it is fast, nondestructive (no sample preparation or sputtering required), matrix independent (unaffected by chemical bonding states), and quantitative (without standards). Thick films of (111)-oriented cubic CVD SiC were compared with (0001)-oriented hexagonal single crystalline SiC, and with single crystalline Si. Elastic Recoil Detection, also referred to as forward recoil scattering (or spectrometry), is an Ion Beam Analysis technique in materials science to obtain elemental concentration depth profiles in thin films. In ERD there is a built-in mass–depth ambiguity which can complicate the analysis of the results. The time evolution of diamond film nucleation and growth have been investigated with SE by Pintér and his co-workers [108]. ERDA experiments are somewhat more challenging for the novice user than are backscattering experiments, as the incident beam is also scattered toward the detector with comparable energy to the forward scattered hydrogen nuclei that are of interest. TOF-ERDA with energetic heavy ions is best suited for the analysis of light elements in thin films between a few nm and ca. Chiang et al. (a) Sketch of the system; (b) Range foil thickness = 3 µm; (c) Range foil thickness = 7 µm; (d) Range foil thickness = 5 µm. Multicomponent, multilayered samples can be analysed. If two or more lighter elements are in the target (in this case vitreous It was found that the presence of atomic hydrogen increased the growth rate by as much as a factor of two. Higher loss tangents were observed for lower-quality diamond films [52]. With an appropriate choice of foil thickness (d), the H and D signals are resolved from each other and from the 4He recoils. Negative ion profiles were recorded due to their sensitivity to fragments originating from oxide matrices. ScienceDirect ® is a registered trademark of Elsevier B.V.

Laitinen, Improvement of Time-Of-Flight Spectrometer for ERDA (Academic Dissertation), University of Jyväskylä, Finland, 2013, From Pukonen et al., J. The parabolic rate constants of the fast oxidizing faces were nearly the same as the parabolic rate constants for single crystalline Si samples. The inset in Figure 12.6 shows the electrical conductivity of a UNCD film (Y axis) as a function of bulk hydrogen concentration (X axis). It was suggested that hydrogen increases the effective surface concentration of nitrogen, but the issue requires further investigation. Sung et al. In the plasma chamber, a bias voltage of –200 V was applied to the Si substrate in a gas mixture of H2 and CH4 to nucleate diamond. ERDA is thus a unique method for determining and depth-profiling light isotopes in the presence of heavier elements. A suitable choice of range foil is essential for these experiments, as it must be thick enough to resolve the spectrum components, but no thicker than necessary, as this leads to increased straggling and decreased depth resolution. Mater. Heavy ions from the accelerator impinge on the target at an angle of between 5° and 45° and recoiled particles are detected at a reaction angle of less than 90° to the incoming beam by two electrostatic timing-mirrors (typically 30–100 cm apart) and an ion-implanted surface barrier energy detector. The masses of successive particles are plotted as ‘banana-shaped’ curves in the TOF energy histogram. Note how the technique is similar to atom probe tomography (discussed in Section 5.5) for the detection of generated ions, but also how it also differs from it for the ion generation. Figure 12.6. If the foil is too thick (c), it completely stops the 4He recoils, but reduces the energy of the hydrogen isotope recoils to the extent that they are not completely resolved. Chiang et al. Short boomerangs, like the O and Ti in Fig. The testing was continued after photographing if complete bleeding of the sample was not observed. Thin 100-nm TiO2 layer on silicon spectrum for recoil time of flight (RToF) using 77-MeV iodine beams. Composition of selected samples was studied with time-of-flight, Chris G. Van de Walle, Noble M. Johnson, in. Figure 8.6. The thicknesses of all ALD coatings reported were within 8% of the nominal thicknesses, as determined by UV-Vis spectrophotometry and XRR from films grown on silicon simultaneously with the steel. By taking the reciprocal of the original resistivity values in Figure 12.5, the curve in Figure 12.6 illustrates the conductivity of the UNCD thin film as a function of hydrogen concentration in the plasma. Smaller amount of grain boundaries exist in diamond films with nanocrystalline (up to a few hundred nanometers in diameter) and microcrystalline (>1 μm in diameter) structures as opposed to UNCD films that exhibit 2–5 nm diameter grains. The energy is measured with either a solid-state or a gas-filled ionisation chamber detector. Although polymers in the direct incident beam suffer from beam damage, the intensity of forward scattered particles is rarely problematic for the range foils, and these typically last for years without any obvious signs of degradation.
