报告摘要：

    Phonons, the quanta of lattice vibrations, are the primary heat carriers for solid-state materials. The demand on effective phonon manipulation in semiconductor multi-layered structures urgently emerges, because of the crucial role of thermal management in semiconductor devices. However, the study on the phonon behavior manipulation has been a long-standing challenge, in particular to demonstrate in experiments. Thanks to the molecular beam epitaxy (MBE) technique that can produce material with atomic-level controllability, we designed and grew a series of semiconductor superlattice structures to explore the phonon transport behaviors. In this talk, a couple of examples designated to manipulate the long wavelength phonons will be presented. In addition to the phonon transport study, an overview of the research interests and device applications of Laboratory of Advance Epitaxy (LAE) at Nanjing University will be introduced for open discussion.
