Chemical trends in high thermoelectric performance proved in pyrite-type dichalcogenides

Prof. Zhang Yongsheng's research group at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has systematically investigated the thermoelectric (TE) properties of three pyrite-type IIB-VIA2 dichalcogenides (ZnS2, CdS2 and CdSe2), and explored their physical mechanisms and several chemical trends.
