The electrical conductivity associated with energy barriers in a polycrystalline semiconductor is derived, taking into account both tunnelling and thermionic emission. Numerical calculations are compared with conductivity data of polycrystalline CdS films, and the contribution of each transport mechanism is determined in a wide temperature interval.
