Recent Progress in the Fabrication, Properties, and Devices of Heterostructures Based on 2D Materials

摘要

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 emerged that provides unprecedented platforms for exploring 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 have been designed and fabricated,including tunneling transistors,photodetectors,and spintronic devices.In this review,we present a summary of the latest progresses in fabrications,properties,and applications of different types of 2D heterostructures,followed by the discussions on present challenges and perspectives of further investigations.
