Pain and temperature dependence of current in polycrystalline ZnGa₂Se₄

Investigation of pain and temperature dependence of current (electrical conductivity) in high-resistance crystalline and amorphous semiconductors provides valuable information about mechanisms of charge transfer, traps and their important parameters. Polycrystalline semiconductors, which are the subject of the present investigations ZnGa₂Se₄, take intermediate position between mono crystallized and amorphous materials. Pain dependence of currents in semiconductors is investigated in electric fields till breakdown at different temperatures. Structures in a planar and sandwich performance, active elements are mono crystals, polycrystalline, amorphous materials and etc. results of the investigation of pain and temperature dependence of current in polycrystalline samples of ZnGa₂Se₄ compounds are submitted in this work first of all
