The deposition rate of hydrogenated amorphous silicon prepared by mercury-sensitized photo-CVD of silanes has been increased through the use of perfluorinated window coatings and small window-substrate separations. Observations regarding the deposition rate and its time dependence are qualitatively explained by a model involving two surfaces with greatly different sticking coefficients for the deposition precursors. The films are characterized by band gap, conductivity, IR absorption, photoluminescence, ESR, and diffusion length measurements.
