Recent research efforts have aimed at discovering thermoelectric materials with high efficiency in the middle-low temperature range, where a majority of waste heat is lost to the ambient. Here, the authors discover colossal Seebeck coefficient values in metallic copper selenide from 340 K to 400 K.
