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 异质结构是在厚度方向实现低导热率的理想候选材料,因为它具有弱的层间相互作用和通过交替堆叠顺序产生的显着无序性。在此,首次将 vdW 异质结构中的热传导解析为单个声子极化的水平,并利用其入射角来阐明声子干扰和声子隧道效应在 vdW 异质结构中的作用。
