Microstructure and electronic properties of hydrogenated amorphous silicon-carbon alloys

Abstract
Transmission-electron-microscopy observations of glow-discharge hydrogenated amorphous silicon-carbon alloys reveal differences in microstructure as a function of the deposition parameter ratio D [D≡(power density)/pressure]. These observations are correlated with infrared absorption, photoconductivity, and density-of-states measurements on these alloys. The electronic properties appear to depend more on trends in carbon bonding than on the types of microstructure.
