Transparent electrode properties of cadmium stannate

Thin films of semiconducting n-type cadmium stannate (Cd2SnO4) have been coated onto different substrate materials by rf sputtering. The films are transparent in the visible and near-infrared part of the optical spectrum and electrically conductive. Conductivities as high as 6500 Ω−1 cm−1 have been achieved. Transparent electrode coatings can be prepared which have 1 Ω/square electrical sheet resistance and 85% average optical transmission between 5000 and 6500 Å.
