  • Optical properties of amorphous Sb2Se3:Sn films 

    Kumar, P.; Sathiaraj, T.S.; Thangaraj, R. (Taylor & Francis, 2010)
    The measurements and analysis of optical transmission and far-infrared (IR) reflectivity spectra of thermally evaporated Sb2Se3:Sn films are reported. The refractive index and film thickness have been determined from ...

  • Phase segregation in Pb:GeSbTe chalcogenide system 

    Kumar, J.; Ahmad, M.; Chander, R.; Thangaraj, R.; Sathiaraj, T.S. (EDP Sciences, 2008)
    Effect of Pb substitution on the amorphous-crystalline transformation temperature, optical band gap and crystalline structure of Ge2Sb2Te5 has been studied. In Pb:GeSbTe chalcogenide films prepared by thermal evaporation, ...

  • Thermal annealing dependence of some physical propertiesof Bi-substituted Sn–Sb–Se glassy thin films 

    Ahmad, M.; Thangaraj, R.; Sathiaraj, T.S. (EDP Sciences, 2009)
    Bulk glasses of the Sn10Sb20−xBixSe70 (0 x 8) system were prepared by the conventional melt quenching technique. Thin films were prepared by the thermal evaporation technique on glass substrates. Appearance of some ...
