Abstract

We report the experimental studies on the thermal deposition of CdTe films. The deposition of thin CdTe films is performed onto the substrate of varying temperature. The characteristics of the deposited CdTe films are studied using Raman spectroscopy, scanning profilometry, and scanning electron microscopy. According to the measurements, thin CdTe films deposited on substrates with temperatures of 300 °C and 450 °C demonstrate the best stoichiometry. The processes of changing the stoichiometric composition of CdTe films were studied by exposing the films to plasma at a high-voltage gas discharge. The optimal regimes were obtained to achieve 5 % excess and 12% deficiency of Te in the fabricated CdTe films. The optical properties of CdTe films in the visible and infrared ranges were studied. We experimentally demonstrate the resonances in spectra of CdTe-based metal-dielectric structures including layers of water, isopropanol, and ethanol, which can be used to determine the concentration of these solvents.
