报告介绍 | 报告摘要:
Thermoelectric materials can directly convert heat into electricity and vice versa. Such materials utilize the Seebeck effect for power generation and the Peltier effect for refrigeration. As the global energy crisis and environment pollution becoming more and more serious, the search for new thermoelectric materials is of important significance. In this talk, the thermoelectric properties of several bulk and low-dimensional systems are investigated by using a multiscale approach which includes first-principles method, Boltzmann theory, molecular dynamics simulations, and etc. Our theoretical works predict very high ZT values for some example systems such as bismuth, black phosphorous, and transition-metal dichalcogenide, which deserve further experimental investigations.
