Ion-beam Sputtering Deposited Cu-doped CdS Thin Film

  Cu-doped CdS thin film has been successfully deposited by ion-beam sputtering deposition.The structural,morphology,optical and electrical properties of as-deposited and annealed Cu-doped CdS thin films were investigated.The heavily Cu-doped CdS films annealed at 400 ℃ was demonstrated to be improved in structural,morphology,electrical and optical properties.X-ray diffraction (XRD) analysis indicated the formation of polycrystalline CdS film with the structure of hexagonal wurtzite phase.No distinct impurity of Cu and Cu-S phase was detected in Cu-doped CdS thin films.Atomic force microscopy (AFM) revealed that the grain size was increased after annealed.Optical transmission and absorption spectroscopy measurement revealed a high absorption and energy band gap was of about 2.40 eV.The CdS thin film was of p-type conductivity and the resistivity was found to be 1.28×10-1 Ωcm.
