Abstract

Plasma- and chemical vapor deposited films containing hydrogen, Si, B and O, but of unknown thickness and stoichiometry have been assigned concentration ratios through a combination of H-profiling using the ¹H(¹⁵N, αγ)¹²C(4.43 MeV) reaction and RBS analysis. Relatively intense ¹⁵N⁺⁺ beams exceeding the 6.38 MeV resonance energy have been obtained from a 3.75 MeV accelerator with a commercial ion source and terminal analysis. A discussion is given of the method of obtaining film concentration ratios in some representative cases. A search was made for H at the SiO₂Si interface. Some preliminary investigations have been made on the H concentration in several metals as supplied: Nb, V, Ta, Al, Ni, OFHC Cu, Ti, Mo and steel and on the effect of acid dips in loading H. Hydrogen in acid-loaded steel migrated under the influence of the probing ¹⁵N beam, but relaxed back when the beam was removed.
