(711a) Panoscopic Engineering of Nanomaterials Formodulated Heat Transfer and Beyond

Modulation of electrical, thermal, and surface properties requires a precise control of the defects over different length scale from atomic level to lattice structure and further extending to the bulk. In the past few years, we have been exploring how to control the heat transfer in nanostructured materials. Through phonon manipulation and band structure engineering we were successful to achieve thermoelectric materials with better performance. We also
learned some hard lessons that the heat transfer in thermal interface can be significantly impinged by surface defects. We turned the failure into opportunity by utilizing the surface defects in 2D metal carbides to obtain bimetallic nanoparticle catalyst based on reactive metal support interaction.
