Study and characterization of copper-indium-ditelluride

In this paper, single crystals of chalcopyrite semiconductor CuInTe/sub 2/ have been grown by a vertical Bridgman technique. The Hall effect, mobility, resistivity and carrier concentration data have been obtained for several samples using the van der Pauw technique. The optical properties were studied by photoacoustic spectroscopy (PAS) in order to determine parameters such as absorption spectra, band gap and defect level states.
