Physical properties of ultrasonic sprayed nanosized indium doped SnO2 films

Here, we report on the preparation and characterization of nanosized indium doped tin oxide films (TO:In). The films are grown by ultrasonic spray pyrolysis deposition (USPD) onto glass. The structural, optical, electrical and morphological properties of SnO2 (TO) films are investigated. The as-depo...

Description
Summary:Here, we report on the preparation and characterization of nanosized indium doped tin oxide films (TO:In). The films are grown by ultrasonic spray pyrolysis deposition (USPD) onto glass. The structural, optical, electrical and morphological properties of SnO2 (TO) films are investigated. The as-deposited films SnO2 have preferred orientation along the (200) plane and are polycrystalline with a tetragonal crystal structure. Following this direction, the average grain size, obtained from XRD patterns, decreases with the rate doping. It ranges from 64 to 17nm. In UV spectrum, the transmittance increases followed by a slight decay within visible range. Optical band gap, E
