Abstract
Two-dimensional (2D) Transition Metal Chalcogenides (TMCs) have attracted tremendous interest from both the scientific and technological communities due to their variety of properties and superior tunability through layer number, composition, and interface engineering. Wafer-scale production of 2D TMCs is critical to the industrial applications of these materials. Extensive efforts have been bestowed to the large-area growth of 2D TMCs through various approaches. In this review, recent advances in obtaining large-area 2D TMCs by different methods such as chemical vapor deposition (CVD), metal-organic CVD, physical vapor deposition are firstly highlighted and their advantages and disadvantages are also evaluated. Then strategies for the control of the grains, morphology, layer number and phase to achieve controllable and uniform thicknesses and large crystal domains for 2D TMCs are discussed. Applications of large-area 2D TMCs in electronics, optoelectronics, spintronics etc. are also introduced. Finally, ideas and prospects for the future developments of wafer-scale 2D TMCs are provided.
