Strong anharmonicity driven wave-like thermal transport and high thermoelectric performance in TlCu5Se3

Thermal transport in crystalline solids generally occurs via particle-like phonon propagation. Here, we demonstrate the dominant unusual wave-like phonon transport and high thermoelectric figure-of-merit (zT) of ∼1.42 at 673 K in crystalline TlCu5Se3 due to the strong anharmonicity exerted by confined Cu dynamic disord...
