摘要:The present invention provides a general salt-assisted chemical vapour deposition method for phase-controllable synthesis of 1T′ and 2H-phase transition metal dichalcogenide (TMD) monolayer crystals. The method comprises: mixing a transition metal compound powder and a salt powder to form a precursor; placing a substrate on top of the precursor; placing the precursor and the substrate at a center position in a chemical vapour deposition (CVD) furnace; placing a chalcogen powder at an upstream position relative to the precursor along a gas-flow direction in the CVD furnace; heating up the CVD furnace to a growth temperature within the heat-up time; keeping the CVD furnace at the growth temperature for a growth time under a mixed gas flow of H2 and Ar. The optical and electrical characterizations reveal the phase-dependent in-plane isotropy and anisotropy of the as-synthesized 2H and 1T′-phase crystals. The 1T′-TMD monolayer crystals demonstrate much-improved phase transition temperatures.

权利人:NANOCO TECHNOLOGIES LTD; NANOCO 2D MAT LIMITED
摘要:A template-assisted method for the synthesis of 2D nanosheets comprises growing a 2D material on the surface of a nanoparticle substrate that acts as a template for nanosheet growth. The 2D nanosheets may then be released from the template surface, e.g. via chemical intercalation and exfoliation, purified, and the templates may be reused.
