Title: A theoretical study of fluorographene as substrates for mono-/Bi-layer graphene

Using density functional theory, we discover fluorographene (CF) could help significantly preserve the superb electronic properties of graphene, depending on lattice stacking-order. Compared with h-BN, CF produces a much weaker screening effect for bilayer graphene when external electric field is applied, revealing a huge advantage in gap engineering. The studies suggest that fluorographene could be a promising route towards implementing highly functional substrate or gate dielectric materials for graphene-inspired device applications.
