ELECTRONIC-STRUCTURE OF SOL-GEL DERIVED SNO2 THIN-FILMS

Ellipsometric measurements on sol gel derived tin dioxide thin films c oated onto various substrates (Quartz, Corning 7059, Float glass, Alum ina and Silicon) have been carried out at air ambient. The imaginary p arts of dielectric spectra have been analyzed and compared with variou s theoretically calculated electronic transitions reported in the lite rature in order to infer the electronic structure of these films.
