anharmonic lattice dynamics under pressure in PbTe
Understanding the influence of anharmonic interaction on lattice-dynamical properties is the key to engineer/design new high-performance thermoelectric materials requiring a low lattice contribution to the thermal conductivity. Here, we propose to investigate the unusual lattice dynamics in seminal thermoelectric PbTe under high pressure. Quantitative molecular simulations by some of us explain the observed anomalous properties at ambient pressure with strong anharmonic influences. Our measurements as a function of pressures up to 6 GPa and a corresponding analysis based on our model will (1) scrutinize the assignment to anharmonic processes, (2) provide a more complete understanding of the intriguing lattice dynamical properties of PbTe, and (3) pave the path for the designs of new high-performance thermoelectric materials.
