Preparation of highly photosensitive hydrogenated amorphous Si-C alloys from a glow-discharge plasma

Abstract
The preparation conditions for the deposition of hydrogenated amorphous silicon‐carbon alloys (a‐SiC:H) from a glow‐discharge plasma have been systematically scanned by changing the starting‐gas materials as well as the starting gas to hydrogen dilution ratio. A highly photosensitive alloy showing a photoconductivity to dark conductivity ratio of 107 at a band gap of 2.0 eV was prepared under optimized conditions.
