Tin-substituted chalcopyrite: an n-type sulfide with enhanced thermoelectric performance

HIGHLIGHTS

• who: Sahil Tippireddy and collaborators from the Central Archive at the University of Reading have published the research work: Tin-Substituted Chalcopyrite: An n-Type Sulfide with Enhanced Thermoelectric Performance, in the Journal: (JOURNAL) of June/25,/2022
• what: The XPS measurements are consistent with the presence of Fe2+ in the tin-substituted chalcopyrite phase, as suggested by the DFT calculations, and the authors propose here that mechanism as the origin of the lower-than-expected increase in carrier concentration on tin substitution. Comparing the u0393 values of Cu0.96Sn0.04FeS2 determined in this study . . .
