A Study of structural and visual features of SnO2 membrane to be prepared Through Evaporation in Space

Abstract

SnO2 thin film has been prepared using vacuum thermal Evaporation technique on glass substrate at room temp . (XRD) spectrum showed that the film was. Polycrystalline and tetragonal . (AFM) measurement showed that the prepared film is nonstructural. It is found that the direct energy gap value is(2.99) eV. The transmittance measurements through the wavelengths range ( 300-1100) nm showed a high value about (85%) due tp the thin film thickens .
