Contributions to the investigation of transport phenomena in amorphous semiconductors

The paper presents the amorphous semiconductors, the experimental investigation of transport phenomena in thin amorphous layers, the theoretical investigation of a model of conduction on localized states at low electric fields, the interpretation of the experimental results at low fields for a-Ge and a-Si, the theoretical investigation of the non-ohmic conduction in a-Ge and a-Si, and the discussion of the results for chalcogenides glasses.
