Abstract

      In this paper, we have reported structural, electrical and optical properties of SnO2 thin film, which are prepared on glass substrate at 350 °C by the chemical spray pyrolysis technique. X-ray diffraction is used to determine the nature of the formed phases. Scanning electron micrographs and Atomic Force Microscopy are performed to examine the surface morphology. It is observed from optical measurement that the optical transmittance (T %) of SnO2 film in visible spectra is found to be 90 % and the calculated energy gap values is around of 3.78 eV. From Hall Effect measurements the electrical resistivity, conductivity, mobility and carrier concentration are respectively found to be 2.11 10-1 (? cm), 4.74 (?.cm)-1, 2.73 (cm2/vs), 1.08 10+19(cm-3).
