Dependence of of thickness F-doped SnO2 films grown by spray pyrolysis technique

Transparent conducting thin films of fluorine-doped SnO₂ were deposited on glass substrates by spray pyrolysis technique in order to find out the effect of film thickness. These films were prepared using fluorine concentrations of 4 mol% at substrate temperature of 500°C. Their electrical resistivity decreased although optical transmittance decreased with increasing the film thickness.
