Synthesis and Optical Properties of Large‐Area Single‐Crystalline 2D Semiconductor WS₂ Monolayer from Chemical Vapor Deposition

Large-area triangular single crystals of WS2 monolayer are synthesised from a chemical vapor deposition process and their optical properties are systematicly studied. This work paves the way to fabricate large-area single crystalline 2D semiconductors and study their fundamentals. It must be very meaningful for exploiting the great potential of WS2 for future optoelectronics.
