Electronic and Optoelectronic Physics in the van der Waals Heterojunctions

Recent advances of van der Waals (vdW) materials and their heterostructures provide a new opportunity to realize atomically sharp interfaces in the ultimate quantum limit. We demonstrate the enhanced electronic optoelectronic performances in the vdW heterostructures, suggesting that these a few atom thick interfaces may provide a fundamental platform to realize novel physical phenomena, such as cross-Andreev reflection across the quantum Hall edges states, and interlayer exciton formation and manipulations.
