Abstract
A tin-cadmium oxide film having an amorphous structure and a ratio of tin atoms to cadmium atoms of between 1:1 and 3:1. The tin-cadmium oxide film may have an optical band gap of between 2.7 eV and 3.35 eV. The film may also have a charge carrier concentration of between 1×1020 cm−3 and 2×1020 cm−3. The tin cadmium oxide film may also exhibit a Hall mobility of between 40 cm2V−1 s−1 and 60 cm2V−1 s−1. Also disclosed is a method of producing an amorphous tin-cadmium oxide film as described and devices using same.
