Simply put, CVD is a way of depositing gaseous reactants onto a substrate. The way CVD works is by combining gas molecules (often using carrier gases) in a reaction chamber which is typically set at ambient temperature. When the combined gases come into contact with the substrate within the reaction chamber … See more CVD graphene is created in two steps, the precursor pyrolysis of a material to form carbon, and the formation of the carbon structure of graphene using the disassociated carbon atoms. The first stage, the pyrolysis … See more In order to create monolayer or few layer graphene on a substrate, scientists must first overcome the biggest issues with the methods that have been observed so far. The first major … See more In terms of overcoming these issues, scientists have been developing more complex techniques and guidelines to follow in order to create the highest quality of graphene possible.
