Abstract

In this paper we present some experimental results concerning the effect of fast electrons irradiation on the specific conduction mechanisms in semiconducting polycrystalline vacuum evaporated CdSe thin layers, in strong electric field, and we give an interpretation of the non-ohmic electrical conduction in these layers. Two conduction regimes defined by the different roles of the intercrystalline barriers and crystallites respectively are analyzed. The changing of some microscopic parameters is calculated from the fitting of the experimental and theoretical I-E characteristics, both for irradiated and unirradiated films.
