摘要

A series of hydrogenated microcrystalline films were grown by a novel thin film deposition method using the Saddle Field Plasma Enhanced Chemical Vapour Deposition system. We show that the surface potential during growth strongly affects the microcrys-talline character of the films, as quantified by Raman scattering. This effect can be reproduced on both conductive and non-conductive substrates. Films grown close to the threshold for microcrystalline growth exhibit laser-induced crystallization at low laser intensities.
