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.
