IntroductionIndium tin oxide (ITO) thin films are wide band gap semicon-ductors with good electrical and optical properties such as lowresistivities (∼10−4 cm), high carrier concentrations, high mobil-ity rates, and high transparency in the visible and near-infraredregions (450–1100 nm), as discussed by Qi et al. (2009) and Chenet al. (2013).
