摘要:

Lattice anharmonic effect plays a crucial role in thermal transport and electron-phonon coupling related physics including electronic transport, superconductivity, polaron, and thermoelectronic properties of strong anharmonic materials. To include cubic and quartic anharmonicity, nonperturbative anharmonic phonon theory is required in calculations of various lattice anharmonicity related properties. Based on the combination of self-consistent phonon theory, compressive sensing techniques, Boltzmann transport equation, electron-phonon coupling, and Migdal-Eliashberg theory, we have investigated lattice thermal conductivity, electron transport, thermoelectronic performance, and superconductivity in a series of strong anharmonic materials, and revealed that the inclusion of anharmonic renormalization in calculations is a significant factor to provide the theoretical findings comparable to experimental results.
