Two-dimensional Janus van der Waals heterojunctions: a review of recent research progresses
摘要：
二维Janus van der Waals（vdW）异质结是指含有至少一种Janus材料的结，由于其固有的极化和独特的层间耦合，具有可调的电子结构、宽的光吸收光谱、可控的接触电阻和足够的氧化还原电位。这些新的结构和性质在电子和能量转换器件中具有潜在的应用前景。本文综述了不同类型二维Janus vdW异质结构的基本性质，包括电子结构、界面接触和光学性质，并讨论了其在电子学和能量转换器件中的潜在应用。最后对新型异质结的进一步研究方向和面临的挑战进行了讨论。
英文摘要：
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.
