Current high-performance thermoelectric materials require elaborate doping and synthesis procedures, particularly in regard to the artificial structure, underlying mechanisms are still poorly understood. Here, we report that a natural chalcopyrite mineral, Cu1+x Fe1-x S2 , obtained from deep-sea hydrothermal vent can directly generate thermoelectricity. The resistivity displayed an excellent semiconducting character, large power high factor were found low x region. Notably, electron-magnon scattering effective mass was detected this region, thus suggesting strong coupling of doped carriers antiferromagnetic spins resulted enhancement properties during mineralization reactions. present findings demonstrate feasibility energy generation electron/hole carrier modulation with abundant Earth's crust.
