BECERRIL, M.; SILVA-LOPEZ, H.; ZELAYA-ANGEL, O.  and  VARGAS-GARCIA, J.R.. Au doping of CdS polycrystalline films prepared by co-sputtering of CdS-Cd-Au targets. Superf. vacío [online]. 2012, vol.25, n.4, pp.214-217. ISSN 1665-3521.

Au doped CdS polycrystalline films were grown on Corning glass substrates at room temperature by co-sputtering from a CdS-Cd-Au target. Elemental Cd and Au were placed onto the CdS target covering small areas. The electrical, structural, and optical properties were analyzed as a function of Au content. The Au doped CdS polycrystalline films showed a p-type semiconductor nature. It was found that the electrical resistivity drops and the carrier concentration increases as a consequence of Au incorporation within the CdS lattice. In both cases, the changes were of several orders of magnitude.
