Modulating charge carrier density and mobility in doped graphene by covalent functionalization

Covalent B-functionalization of B-doped graphene has been performed for the first time. The electronic properties and Hall effect of functionalized N- and B-doped graphene can be tuned by tailoring the electron-donating/-withdrawing properties of the organic addend. We describe for the first time the covalent B-functionalization of B-doped graphene. Besides, the Hall effect can be modulated by the nature of the organic addend.
