SnO₂ has drawn much attention as a promising candidate of transparent electrode because of high optical transparency in the visible region, eco-friendly compositional elements, and high carrier mobility. However, there have been no studies about the thermoelectric properties. In this study, we develop epitaxial SnO₂ films on various kinds of substrates, and also investigate their thermoelectric properties. Furtheremore, by characterizing the device performance, we show the potentiality of SnO₂ film as a thermoelectric material.
