论文摘要
发现二维Janus van der Waals（VDW）异质界面，指的是包含至少一种Janus材料的连接，它们表现出可调的电子结构，宽的光吸附光谱，可控的接触电阻，以及由于内固有的偏振和独特的层间层耦合而引起的足够的氧化还原电位。这些新颖的结构和特性对于电子和能量转换设备的潜在应用是有希望的。为了提供有关研究进度的全面图片并指导以下研究，我们在这里总结了它们在不同类型的二维Janus VDW异质结构（包括电子结构，界面接触和光学特性）的基本特性，并讨论电子和能量转换设备中的潜在应用。在本综述的结尾，讨论了新型异质界的进一步挑战和可能的研究方向。
Two-dimensional Janus van der Waals (vdW) heterojunctions, referring to the junction containing at least one Janus material, are found to exhibit tuneable electronic structures, wide light adsorption spectra, controllable contact resistance, and sufficient redox potential due to the intrinsic polarization and unique interlayer coupling. These novel structures and properties are promising for the potential applications in electronics and energy conversion devices. To provide a comprehensive picture about the research progress and guide the following investigations, here we summarize their fundamental properties of different types of two-dimensional Janus vdW heterostructures including electronic structure, interface contact and optical properties, and discuss the potential applications in electronics and energy conversion devices. The further challenges and possible research directions of the novel heterojunctions are discussed at the end of this review.
