There is much research being conducted on growing high quality CVD graphene on substrates that are important for the microelectronic industry, as well as processes that will allow for the transfer of the materials once produced. The key requirement is to be able to have the highest quality material if dealing ultimately with electronic device applications.

In a recent paper we show how the decoupling of graphene in terms of its carrier transport properties from the growth substrate is critical by hydrogen intercalation. This allows for carrier inversion, Fermi-level shifts and most importantly high carrier mobilities ..... in electronic grade graphene. See ...
