The solid solutions CuInSe2(1-x)Te2x, 0≦x≦1 have been prepared by melting stoichiometric mixtures of constituent elements. They have been characterised by conventional X-ray diffraction techniques and by Electron Probe Microanalysis. The compounds CuInSe2 and CuInTe2 are miscible in all proportions. The solid solutions solidify in the chalcopyrite structure throughout the composition range. The lattice parameters a and c vary parabolically with the composition variable x. © 1985.

The flash evaporation technique produces thin films of stoichiometric CuInTe2. From an analysis of the optical absorption spectra of the thin films, the band gap of CuInTe2 is found to be 1.03 eV. The effect of the background absorption on the absorption spectrum is found to be negligible. The electrical conductivity of these films is limited by hopping conduction in the temperature range 77-200 K. Acceptor levels at 100 meV above the valence band maximum were observed and attributed to copper vacancies. © 1986.
