摘要
We report a convenient chemical vapor deposition (CVD) strategy of two-dimensional (2D) MoS2: the release of Mo vapor is modulated by adjusting the particle size of Al2O3 microsphere powder which uniformly cover on MoO3 precursor, so as to achieve controllable synthesis of MoS2. In this CVD system, Al2O3 is inactive, and the particle size of Al2O3 microsphere is the key parameter of affecting the release amount of Mo vapor. When the particle size of Al2O3 microsphere is 100 nm, a centimeter-scale continuous monolayer MoS2 can be obtained. This work provides a feasible approach to controllably synthesize 2D transition metal dichalcogenides (TMDCs).
