Transparent bipolar oxide semiconductors have been attractive due to their potential application in transparent electronics. Here, we present the synthesis and physical properties of tetragonal-zirconium oxysulfide (t-ZrOS) with a wide optical forbidden band gap. Fluorine and yettorium doping markedly enhanced the conductivity up to ~10-2 Scm-1, in which a clear sign change of Seebeck coefficient was observed. In this meeting, we report not only t-ZrOS but also new semiconducting material based on other novel concept.
