In this work we deposited a series of hydrogenated amorphous carbon (a-C:H) films and nitrogen-doped a- C:H films on silicon substrates using an ion-beam- deposition technique called anode layer source. We used different discharge voltages, which influence the sp2/sp3 carbon hybridization ratio, and we also varied the N2-to- C2H2 flow ratios.

Analysis of hydrogen absorption by Ti and Ti?6Al?4V using the ERDA technique
International Journal of Hydrogen Energy, 2003Abstract Ti and Ti–6Al–4V alloy samples were hydrogenated at different temperatures from 150°C to 750°C. They were analyzed using elastic recoil detection analysis (ERDA) with 3 MeV α particles and Rutherford Backscattering Spectrometry (RBS) with 6.585 MeV α particles. ERDA shows an increase in the amount of hydrogen absorbed

Development of a TOF-ERDA measurement system for analysis of light elements using a He beam
Nuclear Instruments & Methods in Physics Research B, 2010Abstract A time-of-flight ERDA (TOF-ERDA) measurement system has been developed for the analysis of light elements. He ions are used for the incident beam, and recoil light ions are detected with the system. The system consists of a time detector and a silicon detector, and energy and velocity of recoil ion are measured simultaneously.

ERDA of hydrogen and helium using an 8 MeV 16O beam
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1990Abstract An 8 MeV 16O beam was used to profile the depth concentration of 1,2H and 4He implanted into silicon wafers and stainless steel (SUS316). The measured energy spectra of recoiled particles have been unfolded to obtain depth profiles. The TRIM'86 data have been utilized to calculate the response matrix which takes account of the energy loss of

Hydrogen mobility in diamond studies using HI-ERDA microscopy
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1997Abstract Hydrogen plays a significant role in the growth of diamond and in the determination of its physical, electrical and optical properties. However, despite this significance, the configuration, chemistry and behaviour of hydrogen in the diamond lattice is still not very well understood.

Light element analysis using ERDA method with an ionization chamber
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001Abstract An elastic recoil detection analysis (ERDA) system using ΔE−E technique was assembled for stoichiometric and depth profile studies of materials formed by light elements. An ionization chamber with a surface barrier detector (SBD) was used in this work.

Heavy ion-induced desorption investigations using UHV-ERDA
Vacuum, 2007Abstract Ion–beam-loss induced desorption is a well known intensity limitation for high current, low charge state heavy ion accelerators like the heavy ion synchrotron SIS18 at GSI. Therefore dedicated measurements of desorption yields has been made, e.g., at CERN and at GSI in the last few years. In this work we will present studies performed at GSI

Optimization of the depth resolution in ERDA of H using 12C ions
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1994Abstract Depth resolution is one important parameter in the depth profiling of H by elastic recoil detection analysis (ERDA). We report on depth resolution measurements and compare them with those calculated by the DEPTH code [E. Szilagyi and F. Paszti, these Proceedings (IBA-11, Balatonfured, Hungary, 1993) Nucl. Instr. and Meth. B 85 (1994) 616; E.

Element-dependent ERDA probing depths using different detection systems
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1997Abstract Elastic Recoil Detection Analysis (ERDA) of a pyrex-glass sample is carried out in the elemental range of Z=5–20 using element dispersive ionization chambers and a time-of-flight (TOF-E) system, respectively. It is shown that recoil identification with the gas detectors is limited to energies significantly higher than the values assigned to ...

Behavior of Li on graphene surfaces observed using high-resolution ERDA
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2016Abstract Behavior of Li atoms deposited on the surfaces of highly oriented pyrolytic graphite (HOPG) and graphene-based thin films were observed at room temperature using high-resolution elastic recoil detection analysis (ERDA). On the HOPG surface, the deposited Li atoms intercalate into the bulk and no Li was observed in the surface region.
