Thermoelectric Enhancement of Ternary Copper Chalcogenide Nanocrystals by Magnetic Nickel Doping

Abstract

The substitution of Cu+ in Cu3SbS4 nano­crystals by magnetic Ni2+ increases electrical conductivity while nearly retaining the Seebeck coefficient, due to the spin effect. This demonstrates that the substitution of Cu+ by Ni2+ can notably improve the thermoelectric performance of a ternary Cu3SbS4 system.
