Abstract
An optical band-gap shrinkage was found in highly transparent and cond ucting thin films deposited by the Pyrosol Process. The narrowing appe ars at carrier concentrations which are consistent with a metal-semico nductor transition. The gap-shrinkage dependence on carrier concentrat ion is consistent with the model proposed by P E. Schmid [Phys. Rev. B 23, 5531 (1981)] for Si:As and Si:B.
