Overview on Transparent Conducting Oxides and State of the Art of Low-cost Doped ZnO Systems

Transparent conducting oxides (TCOs) have become an integral part of modern life through their essential role in touch screen technology. The growing demand for cheap and superior transparent conducting layers, primarily driven by the smart phone market, has led to renewed efforts to develop novel TCOs. Currently, the most widely used material for transparent conducting applications is Sn-doped indium oxide(ITO)
