Design and synthesis of two-dimensional materials and their heterostructures

Abstract

The advent of two-dimensional (2D) materials has attracted extensive attention in recent years because of their versatile properties like high carrier mobility, optical transparency, good flexibility, and sizeable bandgap. Thus these 2D materials have attracted tremendous attention for fundamental research and novel device applications. Due to the nature of weak Van der Waals (vdW) interlayer interaction, these materials provide a unique opportunity to build high quality and atomically sharp heterostructures. The preparation of the large-area and high-quality hybrid 2D materials has become a very urgent topic for study. Thus great efforts have been made to promote the investigation of the fascinating properties and broad applications of these heterostructures. These heterostructures can be synthesized by either stacking one layer over the other vertically or by stitching together in a plane laterally. In this chapter, we will discuss in detail on the synthesis of novel 2D materials and their heterostructures. © 2020 Elsevier Inc.
