Nucleation of Microcrystallites in Phosphorus-Doped Si:H Films

Abstract
Structural properties of partially crystallized Si:H films prepared by glow discharge technique have been studied by Raman scattering and optical absorption spectra. The structure of the Si:H films is found to be a mixture of microcrystalline and amorphous phases. The volume fraction of a microcrystalline part in the Si:H network was determined to be 0.37–0.58 on the basis of the effective-medium theory.
