シミュレーションによる多元系熱電材料Cu2ZnSnS4の熱電変換効率の評価

抄録

Cu2ZnSnS4 (CZTS) single crystal is a high-performance thermoelectric material while using environmentally friendly materials. In this study, we investigated the impact of grain-boundary on thermal conductivity and the improvement of conversion efficiency in CZTS by the combination of experimental and theoretical results.
