Abstract

Nuclear magnetic resonance (NMR) measurements of H-1 in samples of hydrogenated amorphous silicon made by the very-high-frequency (70 MHz) glow discharge (VHFGD) technique show that the local hydrogen bonding is very similar to samples made by the ordinary r.f glow discharge (RFGD) technique. Differences observed between RFGD and VHFGD samples in experiments such as hydrogen evolution or infrared spectroscopy are therefore due to differences in the longer-range order. In addition, spin-lattice relaxation measurements of the bonded hydrogen as a functionof temperature indicate that the total concentration of trapped molecular hydrogen (H-2) in the VHFGD films is most probably also similar to that observed in the RFGD samples.
