Description
Summary:In order to obtain CdIn sub(2)Te sub(4) thin films, (CdTe) sub(1-x)(In sub(2)Te sub(3)) sub(x) thin films were grown on glass substrates by the close spaced vapor transport combined with free evaporation technique (CSVT-FE) using coevaporation of CdTe and In sub(2)Te sub(3). When the saturation limit of In in the CdTe structure is achieved, a CdIn sub(2)Te sub(4) thin film is obtained. Indium incorporation is controlled by the temperature of the In sub(2)Te sub(3) source. The composition of the films was investigated by Auger electron spectroscopy and X-ray diffraction was used to evaluate the structural transition of the films from CdTe (zincblend) to CdIn sub(2)Te sub(4) (tetragonal). Optical characterization by Raman, transmission and photoreflectance spectroscopies gave us further evidence of the success in the production of CdIn sub(2)Te sub(4) thin films.
