内容简介：Heat transfer engineering has attracted tremendous attention in the recently years due to its importance in many fields, such as thermoelectrics, heat dissipation and so on. In this talk, I will present our recently work on thermal conductivity engineering in nanostructures, including twinning superlattice (SL) NWs, antiphase SL NWs, dislocated NWs and resonant nanostructures. With a combination of Molecular Dynamics, Lattice Dynamics and Green’s Function technique, we aimed to discuss the detailed mechanisms of each type of nanostructure, especially the resonant structures. The phonon resonant mechanism can effectively block the low frequency phonons, which is difficult to be treated by phonon scattering mechanism. Thus the phonon scattering and resonant mechanisms can complement each other in engineering the thermal transport.
