Abstract
In this work, in order to investigate the impact of substrate temperature on structural and optical properties of CdTe thin films, four specimens with different substrate temperatures (100, 200, 300 and 400°C) were prepared. Structural and optical properties of the samples were systematically studied by X-ray diffraction (XRD), Atomic Force Electron Microscopy (AFM) and UV-Vis spectrophotometer techniques. XRD studies revealed the cubic phase for the deposited samples. AFM images of the specimens showed the increment of grain size upon substrate temperature increase. The results show that the substrate temperature has an important role in tuning the optical properties of nano-crystalline structure of the samples.
