Role of chemical doping on the enhancement of thermoelectric performance in metal-based thermoelectric system SnCCo3

We systemically investigated the effects of chemical doping on thermoelectric properties of antiperovskite metal-based thermoelectric materials Sn1−xMxCCo3 (M = Ag, In, Ge, Pb, Sb), and found an enhancement of thermoelectric performance induced by hole doping.177
