Abstract:Tin-doped ZnO (TZO) thin films with various tin concentrations (0, 1, 2, 3, 4, and 5 atomic percent [at. %]) are prepared by the sol-gel dip-coating method. The doping effects of tin on the structural and optical properties of the TZO thin films are investigated. All the samples have a granular structure consisting of small particles and exhibited a preferred c-axis orientation. The transmittance and optical band gap of the TZO thin films increase at relatively low tin concentrations of 1-2 at. %, whereas they… Show more
