Abstract

This paper presents results of the transmittance, photoacoustic and surface photovoltage experiments performed on the series of CdS1 – xTex thin films. These CdS1 – xTex (0 ≤ x ≤ 1) thin films were obtained on the glass substrate by the chemical molecular beam deposition (CMBD) method. From the experimental optical characteristics, the optical absorption coefficient spectra of the samples and values of the energy gaps vs. composition of the crystals were determined. The energy gaps of the layers changed from 2.44 to 1.34 eV. From the photo voltage characteristics, the diffusion lengths of the carriers were determined. They changed from 5 to 17 µm what can indicate a good quality of the layers.
