项目摘要
VdW heterostructures are an ideal candidate to realize low thermal conductivity in their through-thickness direction due to its weak interlayer interactions and prominent disorder by alternating stacking orders. Herein, for the first time, heat conduction in vdW heterostructures are resolved to the level of individual phonon polarizations, whose incident angles are utilized to elucidate the role that phononinterference and phonon tunneling play in vdW heterostructures.
VDW异质结由于其弱的层间相互作用和通过改变堆积顺序而产生的明显的无序性,是实现其厚度方向低热导率的理想候选者。本文首次将VDW异质结中的热传导解析为单个声子极化的水平,并利用声子极化入射角度来阐明声子干涉和声子隧穿在VDW异质结中的作用。
