2D transition metal chalcogenides have attracted significant interest due to their tunability and variety of properties. This review discusses recent advances in obtaining large-area 2D TMCs through different methods, strategies for controlling various aspects of the materials, applications in electronics, optoelectronics, spintronics, and provides ideas and prospects for future developments.
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, and physical vapor deposition are first 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.
