Silicon oxide films were deposited on crystalline gallium arsenide substrat
es by chemical vapor deposition (CVD) using a solid source of silicon dioxi
de and atomic hydrogen as reactant, Infrared (LR) absorption spectra of the
samples showed the characteristic bands of Si-O-Si group, typical of SiO2,
and SiH group, but could not detect any band corresponding to OH or SIGH g
