Abstract

Abstract : In article number1803092, Qingyu Yan, Mercouri G. Kanatzidis, and co‐workers develop a bottom‐up self‐assembly process to prepare CuSbSe2 ‐PtTe2 based pellets with highly oriented single‐crystalline nanoplates, which results in an orientation factor of ≈0.8 for (00l) facets. The texture engineering and carrier concentration optimization enable an ≈500% enhanced ZT value (0.50 at 673 K) for CuSbSe2 ‐2.0 mol% PtTe2 compared to pure CuSbSe2 .
