Abstract
Polycrystalline CuIn1âxGaxTe2 bulk films were synthesized by reacting, in stoichiometric proportions, high purity Cu, In, Ga and Te in a vacuum sealed quartz ampoule. The phase structure and composition of the bulk films were analysed by X-ray diffraction and energy-dispersive X-ray analysis, respectively. The bulk samples, of p-type conductivity, are found to be near-stoichiometric, polycrystalline, with tetragonal chalcopyrite structure, predominantly oriented along a direction perpendicular to the (1Â 1Â 2) plane. Photoluminescence spectra were recorded at 7Â K and 700Â mW to characterize the defects and the structural quality. The main peak as a function of composition has been studied.
