Abstract :
The Mn, Sb and Se doped CdS thin films have been prepared using vacuum thermally evaporated mixed powders. XRD, AFM, optical spectroscopy and electrical measurements investigated the films deposited onto glass and silicon wafer substrates. The thin films have a textured hexagonal structure and after a heat treatment at 723 K become all transparent and have a low reflectivity. The CdS thin films doped with Sb and Se perform a relatively high electrical conductivity.
