Transparent Conducting Pure and Tin Doped Indium Oxide Films - Preparation and Characterization

Badeker in 1907 observed that some materials are optically transparent in the visible light and electrically conducting [1]. Because of the increasing interest in electrically and electronically active materials the search for materials and the techniques for producing semi-transparent electrically conducting films have gained much importance. In an intrinsic stoichiometric material it is not possible to have simultaneously high transparency (>80%%) in the visible region and high electrical conductivity (>103 Ω cm-1). A variety of metals in thin film form (
