Heterogeneous Integration of 2D Materials: Recent Advances in Fabrication and Functional Device Applications

Abstract

A comprehensive review of the fabrication process, fundamental properties and functionalities and device applications of heterogeneously integrated two-dimensional (2D) materials is provided. An extensive library of atomic 2D materials with selectable material properties exists and it is rapidly expanding, with which it is possible to construct hybrid or heterostructures that display novel properties with unique functionalities. Such heterostructures adding a degree of freedom to carriers in the third direction provide interesting possibilities for the design of functional novel devices. The subject of 2D heterostructures has now become so vast that no single article can cover the entire topic in any reasonable manner. This review is intended to bridge the gap between the major developments already discovered and current trends in 2D heterostructures.
