To investigate pathways to adjust the charge carrier concentration and optimize thermoelectric properties, we characterized structural thermal stability, performance of pristine Cl-doped Cu5+εSn2−εS7. We demonstrate that Cl doping in Cu5Sn2S7-type monoclinic compounds induces a collapse long-range cationic ordering, ultimately leading sphalerite-type cubic phase by ordered [Sn(S,Cl)4]x clusters...
