Abstract: Chemical Vapour Deposition (CVD) has emerged as a workhorse for the production of graphene [1,2] and more recently applied in the synthesis of other 2D materials such as hexagonal Boron Nitride [3] and Molybdenum Disulphide [4]. In this talk, I will present an overview of our tool and process capabilities via CVD to synthesize graphene and hexagonal Boron Nitride (hBN) and plasma enhanced CVD techniques to synthesize nanocrystalline graphene(NCG) and vertically grown graphene. The synthesized structures were characterized using Scanning Electron Microscopy(SEM), Atomic Force Microscopy (AFM), Raman spectroscopy and X-ray Photoelectron Spectroscopy(XPS). The range of 2 dimensional nanostructures grown by this technique demonstrates the versatility of chemical vapour deposition based routes for the fabrication of these materials.
