Preparation and Properties of Copper Indium Diselenide CuInSe_2

摘要

Polycrystalline alloys in the Cu-In-Se ternary system of specified compositions are synthesized using an original silica apparatus designed by the authors and the temperature-time conditions also specially chosen for this synthesis.The region of existence of CuInSe_2-based solid solutions in the Cu-In-Se system,the temperature of the polymorphic transformation of the CuInSe_2 compound from the chalcopyrite modification into the sphalerite modification,and the melting temperature of the sphalerite modification are determined experimentally.
