Abstract
In article number 1803092, 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.
