Homogenizing a liquid-like Cu sublattice for high-performance Cu<sub>2</sub>Te<sub>0.5</sub>Se<sub>0.5</sub> thermoelectric materials
We homogenize liquid-like Cu atoms via phase-dependent diffusion and quenching, suppressing clustering and vacancies by freezing a uniform Cu sublattice, thereby significantly reducing carrier concentration and lattice thermal conductivity.
