Abstract

Graphene is widely used in photodetection because of its high carrier mobility and wide spectral absorption range. However, its high dark current caused by its low light absorption severely limits its performance. Molybdenum dihalide (MoX₂, X= S, Se and Te) has a high absorption coefficient, which can compensate for the high dark current in graphene-based photodetectors and result in outstanding photoelectronic properties of those based on a graphene/MoX₂ van der Waals heterostructure (vdWH). In this review, we firstly review working principles, performance indicators, and structures of photodetectors. After that, the significance of graphene/MoX₂vdWH photodetectors is highlighted from the fundamental perspective. Preparation methodologies and performance enhancement strategies of graphene/MoX₂vdWH photodetectors are correspondingly summarized. In the end, we highlight the current challenges and future directions of the graphene/MoX₂vdWH photodetectors. This review will guide the design of high-performance vdWH photodetectors.

基于石墨烯/二卤化钼的范德华异质结构光电探测器的研究进展

石墨烯具有高载流子迁移率和宽光谱吸收范围，因此被广泛应用于光电探测领域。然而，石墨烯对光的吸收率低导致暗电流大，严重限制了其性能。二卤化钼（MoX2，X= S、Se 和 Te）具有较高的吸收系数，可以弥补石墨烯基光电探测器的高暗电流，从而使基于石墨烯/MoX2 范德华异质结构（vdWH）的光电探测器具有出色的光电特性。在这篇综述中，我们首先回顾了光电探测器的工作原理、性能指标和结构。然后，从基础角度强调了石墨烯/MoX2vdWH 光电探测器的意义。相应地总结了石墨烯/MoX2vdWH 光电探测器的制备方法和性能增强策略。最后，我们强调了石墨烯/MoX2vdWH 光电探测器目前面临的挑战和未来的发展方向。本综述将为高性能 vdWH 光电探测器的设计提供指导。

期刊介绍： New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
