Binary compound semiconductor of (CdS) and copper doped (CdS:Cu) thin films have been deposited onto glass substrates at substrate temperature (T =653 K) by spray technique. Different doped films were prepared using different concentrations of Cu (0.1-2%). The effect of copper doping on some physical properties of the prepared films of thickness (0.9 ± 0.05 µm) was investigated. The structural, optical and electrical properties of the films have been studied using X-ray diffraction, optical transmission spectra and electrical conductivity respectively. These properties were found to be stron...
