Thermoelectric Performance Enhancement in Off-Stoichiometric Ag–Se Alloys via Composition Imbalance and Vacancy Suppression

Abstract This study investigates the thermoelectric performance of off-stoichiometric Ag–Se alloys through composition-imbalance engineering. By varying the Ag-to-Se ratio, we successfully tuned the carrier concentration and mobility by suppressing Se-vacancy formation and reduci...
