Effective density of states profiles of heterogeneous microcrystalline silicon

The steady state photoconductivity as a function of temperature and light intensity was measured on plasma deposited highly crystalline undoped hydrogenated microcrystalline silicon films possessing different thicknesses and microstructures. Different phototransport behaviors were observed experimentally in films having dissimilar microstructural attributes. This has been explained by numerical modeling to link these behaviors to different features of the proposed density of states maps of the material.
