Modern electronics heavily rely on the technology to confine electrons in the interface layers of semiconductors. In recent years, scientists discovered that various atomically thin van der Waals (vdW) layered materials can be isolated. In these atomically thin materials, quantum physics allows electrons to move only in an effective 2-dimensional (2D) space. By stacking these 2D quantum materials, one can also create atomic-scale heterostructures with a wide variety of electronic and optical properties. We demonstrate the enhanced electronic and optoelectronic performances in the vdW heterostructures, suggesting that these a few atom thick interfaces may provide a fundamental platform to realize novel physical phenomena. In this talk, we will discuss several research efforts to realize unusual quasiparticle pairing mesoscopic devices based on stacked vdW interfaces between 2-dimensional materials.
现代电子产品严重依赖将电子限制在半导体界面层中的技术。近年来，科学家发现各种单原子层厚的由范德华力（vdW）分层的材料可以被分离出来。在这些单原子层厚的材料中，量子物理学将这些电子局限在有效的二维空间中移动。 通过堆叠这些二维量子材料，还可以创造出具有迥异的电子和光学特性的原子级异质结构。我们展现了范德华异质结构的增强的电子和光电性能，表明这种几个原子层厚度的界面可能为实现新的物理现象提供了基础平台。在本次讲座中，我们将讨论基于二维材料间堆叠的范德华界面实现非常规准粒子配对介观器件的一些研究工作和进展。
