Abstract
In order to obtain CdIn2Te4 thin films, (CdTe)(1-x)(In2Te3)(x) thin films w ere grown on glass substrates by the close spaced vapor transport combined with free evaporation technique (CSVT-FE) using coevaporation of CdTe and I n2Te3. When the saturation limit of In in the CdTe structure is achieved, a CdIn2Te4 thin film is obtained. Indium incorporation is controlled by the temperature of the In2Te3 source. The composition of the films was investig ated by Anger electron spectroscopy and X-ray diffraction was used to evalu ate the structural transition of the films from CdTe (zincblend) to CdIn2Te 4 (tetragonal). Optical characterization by Raman, transmission and photore flectance spectroscopies gave us further evidence of the success in the pro duction of CdIn2Te4 thin films. (C) 2000 Elsevier Science S.A.
