|Abstract:||A method for quantitative analysis of hydrogen distribution in 3D has been developed using the elastic recoil detection analysis (ERDA) technique in conjunction with a nuclear microprobe. 2-3 MeV alpha particles, focused down to 2-5 μm, were applied at incident angles of 10-15° to the sample surface. Using an absorber placed in front of surface barrier (SB) detector in order to stop forward-scattered alpha particles, we have achieved a hydrogen detection limit of about 0.1 at.% and a depth resolution of about 80-100 nm. The technique was applied simultaneously with Rutherford backscattering spectrometry (RBS) to measure and image the hydrogen distribution in thin films and solid state bulk materials.|
