In the paper we report some theoretical results on the thickness and temperature dependences of the electrical conductivity and band gap width for semiconducting thin films. The expressions for electrical conductivity and energy gap are deduced as functions of the scattering parameter of film surfaces, potential in surface layer, mean free path of charge carriers, thickness of the surface layer, film thickness, temperature, and some characteristic parameters of the bulk material.
