Evidence of tuned anharmonicity in the thermoelectric material Cu2-x S

Evidence of tuned anharmonicity in the thermoelectric material Cu2-x S

Abstract The mechanisms underlying the low thermal conductivity of Cu2-x (S, Se) have been attracting considerable attention. However, Cu defects in Cu2-x (S, Se) have been reported to lead to an unusual increase in lattice thermal conductivity, unlike the typical decrease caused by phonon scatterin...
