In this work, the Ni/Co/Si system was annealed at temperatures ranging from 300 °C to 800 °C. The samples were characterized by means of X-ray diffraction (XRD), Raman spectroscopy, Rutherford backscattering spectroscopy (RBS), atomic force microscopy (AFM) and sheet resistance measurement. The XRD and Raman spectroscopy results showed that the formation of nickel and cobalt silicides (CoSi, Co2Si,...
This paper describes the possibilities of obtaining nanostructured TiO2 using Spray Pyrolysis Deposition and its application in a solid state solar cell (FTO/ TiO2 In2S3/ CuSbS2/ graphite). Nanostructured TiO2 films are deposited from ethanolic solution of titanium (IV) isopropoxid, (TTIP, 99.99%, Sigma-AIdrich), and acetilacetonate, (AcAc, 99+%, Aldrich); two parameters are proposed for investigation:...
In this paper, nonmagnetic elements (Al and Cu) doping effect on the structural and magneto-transport properties of Zn0.85Mn0.15O (ZnMnO) dilute magnetic semiconductors were reported. The structural characterization was performed using XRD, Raman spectroscopy, AFM and SEM. Temperature dependent electrical resistivity, Hall effect, and were carried out using a standard magneto-transport set-up.
