Charge Transport and Thermoelectric Performance of Bornite Controlled by Cu Non-Stoichiometry
Cu-deficient bornite Cu5−xFeS4 (x = 0–0.20) samples were synthesized by mechanical alloying (MA) followed by hot pressing (HP) to investigate the effects of Cu-site non-stoichiometry on structural evolution, charge transport, and thermoelectric performance. X-ray diffraction confirmed single-phase bornite formation aft...
