Zusammenfassung:Disclosed is a thermoelectric material according to various SSnSe-based formulas, and the systems and methods of manufacturing the thermoelectric, high performance material by hot pressing materials according to various formulas in order to obtain a figure of merit (ZT) suitable for thermoelectric applications at high (above 600K) temperatures. A disclosed method comprises hot-pressing a powder that comprises Sn and Se in a predetermined direction to form a pressed component, wherein the pressed component comprises a ZT value of at least 0.8 above about 750 K.
