Advances in graphene/molybdenum dichalcogenide-based van der Waals heterostructure photodetectors
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.
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.
