2019，Recent progress in the fabrication, properties, and devices of heterostructures based on 2D materials
Abstract
With a large number of researches being conducted on two-dimensional (2D) materials, their unique properties in optics, electrics, mechanics, and magnetics have attracted increasing attention. Accordingly, the idea of combining distinct functional 2D materials into heterostructures naturally emerges and provides unprecedented platforms to explore new physics that are not accessible in a single 2D material or 3D heterostructures. Along with the rapid development of controllable, scalable and programmed synthesis techniques of high-quality 2D heterostructures, various heterostructure devices with extraordinary performance are designed and fabricated, including tunneling transistors, photodetectors, and spintronic devices and so on. In this review, we give a summary of the latest progress in fabrications, properties, and applications of different types of 2D heterostructures, and point out the present challenges and bring up our perspective on the further investigations.
