Abstract Being a representative candidate from the two-dimensional (2D) materials family, graphene has been one of the most intensively researched candidates because of its ultrahigh carrier mobility, quantum Hall effects, excellent mechanical property and high optical transmittance. Unfortunately, the lack of a band gap makes graphene a poor fit for digital electronics, where the current on/off ratio is critical. Huge efforts have been advocated to discover new 2D layered materials with wonderful properties, which complements the needs of 2D electronics. Appropriately designed graphene based hybrid structure could perform better than its counterpart alone. The graphene hybrid structure soon become one of the most exciting frontiers in advanced 2D materials, and many efforts have been made to create artificial heterostructures by assembling of graphene with various layered materials. In this review, we present the recent development in synthesis and applications of graphene based 2D heterostructures. Although 2D transition metal dichalcogenide semiconductors have been demonstrated as strong candidates for next-generation electronics and optoelectronics, by combining advantages of various properties of 2D materials together with graphene, it is highly possible to build entire digital circuits using atomically thin components, and create many novel devices that can be utilized in different areas.

石墨烯/过渡金属二硫属化物扁平封装组件的合成与光电应用

摘要 作为二维 (2D) 材料家族的代表性候选材料，石墨烯因其超高的载流子迁移率、量子霍尔效应、优异的机械性能和高透光率而成为研究最深入的候选材料之一。不幸的是，缺乏带隙使得石墨烯不适合数字电子产品，其中电流开/关比至关重要。人们已经付出了巨大的努力来发现具有奇妙特性的新型二维层状材料，这补充了二维电子产品的需求。适当设计的基于石墨烯的混合结构可以比单独的对应物表现得更好。石墨烯混合结构很快成为先进二维材料中最令人兴奋的前沿领域之一，通过将石墨烯与各种层状材料组装在一起，已经做出了许多努力来创造人造异质结构。在这篇综述中，我们介绍了基于石墨烯的二维异质结构的合成和应用的最新进展。尽管二维过渡金属二硫属化物半导体已被证明是下一代电子和光电子学的有力候选者，但通过将二维材料的各种特性与石墨烯相结合，很有可能使用原子级薄的组件构建整个数字电路，并创造许多可用于不同领域的新型设备。
