The substitution of Cu + in Cu 3 SbS 4 nanocrystals by magnetic Ni 2+ increases electrical conductivity while nearly retaining the Seebeck coefficient, due to the spin effect. This demonstrates that the substitution of Cu + by Ni 2+ can notably improve the thermoelectric performance of a ternary Cu 3 SbS 4 system.
