Abstract

Thin film samples of hydrogenated amorphous silicon carbide with varying carbon content were prepared by conventional plasma deposition from an SiH4-CH4 gas mixture. Optical transmission and reflection spectroscopy together with constant-photoconductivity measurements show that the widening of the optical gap with increasing carbon content is accompanied by an increased optical absorption at lower energies.
