Description
Summary:We report a new hydrogen flame synthesis method to successfully grow graphene on h -BN flakes in 20 seconds without using any catalyst. At the initial stage graphene layers anchored to the (1&cmb.macr;100) surface plane of the h -BN crystal, and afterwards the graphene grew up beyond substrates to form high electrical conductivity quasi-freestanding nanosheets. Quasi-freestanding graphene rooting on h -BN flakes was successfully prepared by a new hydrogen flame synthesis method in 20 seconds without using any catalyst.
