Polycrystalline SnSe with a thermoelectric figure of merit greater than the single crystal

Nature Materials, Published online: 02 August 2021; doi:10.1038/s41563-021-01064-6SnSe has a very high thermoelectric figure of merit ZT, but uncommonly polycrystalline samples have higher lattice thermal conductivity than single crystals. Here, by controlling Sn reagent purity and removing SnOx impurities, a lower thermal conductivity is achieved,...
