Synthesis and Electronic Devices of Atom-thin Transition Metal Dichalcogenides

We demonstrated a universal bottom-up method to produce more than 40 different species of atom-thin, large-scale and high-quality two-dimensional (2D) crystals (Figure 1) [1]. In the last decade of 2D material research, only a few species such as graphene, h-BN and MoS2 can be directly produced from bottom-up techniques. The difficulty in producing a wide range of 2D materials that are theoretically predicted stem from the precise control of the mass flux and growth rate.
