Enhanced thermoelectric properties of AgSbTe2 obtained by controlling heterophases with Ce doping

Scientific Reports, 2017
We report the enhanced thermoelectric properties of Ce-doped AgSbTe2 (AgSb1−xCexTe2) compounds. As the Ce contents increased, the proportion of heterophase Ag2Te in the AgSbTe2 gradually decreased, along with the size of the crystals.
