AB  - Structural and optical properties of CdTe thin films were investigated applying atomic force microscopy (AFM), XRD powder technique, Raman spectroscopy and far–infrared spectroscopy. CdTe thin films were prepared by using thermal evaporation technique. In the analysis of the far – infrared reflection spectra, numerical model for calculating the reflectivity coefficient for system which includes films and substrate has been applied. Effective permittivity of film mixture (CdTe and air) was modeled by Maxwell – Garnet approximation. We reveal the existence of surface optical phonon (SOP) mode and coupled plasmon-SOP modes (CPSOPM). © 2018 Elsevier B.V.

AB  - Thin films of Se-CuSe2  of three different thicknesses have been prepared by vacuum evaporation method on a glass substrate at room temperature. Surface morphology was investigated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The structural characterization of thin film was investigated using Xray diffraction pattern (XRD). The presence of twophase system is observed. One is the solid solution of Cu in Se and the other is lowpressure modification of CuSe2 . The optical properties of the films were investigated by photoluminescence spectroscopy and UV-VIS spectroscopy. CuSe2  exhibits both direct and indirect transitions. According to UV-VIS measurements, the band gap for direct transition is found to be in the range of 2.72–2.75 eV and that for indirect transition is in the range of 1.71–1.75 eV. On the other hand, selenium exhibits direct band gap in the range 2.33-2.36 eV. All estimated band gaps slightly decrease with the increase of the film thickness. Photoluminescence spectra of thin films show emission peaks at about 1.6 and 2.3 eV nm at room temperature, with no observed shift with decreasing temperature. A model is proposed for explaining such anomaly

AB  - This paper describes the structural and optical properties of Cu-Se thin films. The surface morphology of thin films was investigated by atomic force microscopy (AFM) and scanning electron microscopy (SEM). Formation of Cu-Se thin films is concluded to proceed unevenly, in the form of islands which later grew into agglomerates. The structural characterization of Cu-Se thin film was investigated using X-ray diffraction pattern (XRD). The presence of two-phase system is observed. One is the solid solution of Cu in Se and the other is low-pressure modification of CuSe2. The Raman spectroscopy was used to identify and quantify the individual phases present in the Cu-Se films. Red shift and asymmetry of Raman mode characteristic for CuSe2 enable us to estimate nanocrystal dimension. In the analysis of the far infrared reflection spectra, numerical model for calculating the reflectivity coefficient of layered system, which includes film with nanocrystalite inclusions (modeled by Maxwell -Garnett approximation) and substrate, has been applied.
