Electronics and Optoelectronics Based on Two-Dimensional Materials

Recently, with the emergence of two-dimensional (2D) materials such as graphene, transition metal dichalcogenides, and hexagonal boron nitride, various studies on electronic and optoelectronic devices based on them have been carried out. In this review article, we discuss the representative studies on electronic and optoelectronic devices based on 2D materials and their heterostructures. Accordingly, we briefly overview the unique properties of typical 2D materials and their van der Waals heterostructures and thereafter present an in-depth review of their advantages for electronics and optoelectronics. The opportunities and challenges presented by them for future electronics and optoelectronics are discussed.
