ChemInform Abstract: Thermoelectric Transport in Cu7PSe6with High Copper Ionic Mobility.
The copper ion conducting argyorite-type title compound is synthesized from the elements (evacuated quartz ampule, 1323 K, 3 h, and 773 K, 72 h) and its thermoelectric transport properties are studied.
High Electron Mobility and Disorder Induced by Silver Ion Migration Lead to Good Thermoelectric Performance in the Argyrodite Ag8SiSe6
Superionic chalcopyrites have recently attracted interest in their use as potential thermoelectric materials because of extraordinary low thermal conductivities. To overcome long-term stability issues in thermoelectric generators using superionic materials at evaluated temperatures, materials need to be found that show good thermoelectric performance at moderate temperatures. Here, we present the structural and thermoelectric properties of the argyrodite Ag8SiSe6, which exhibits promising thermoelectric performance close to room temperature.
