We present an ab-initio study of electron mobility and electron-phonon coupling in chemically modified graphene, considering fluorinated and hydrogenated graphene at different percentage coverage. Hexagonal boron carbon nitrogen is also investigated due the increased interest shown by the research community towards this material. In particular, the deformation potentials are computed by means of density functional theory, while the carrier mobility is obtained according to the Takagi model (S. Takagi, A. Toriumi, and H. Tango, IEEE Trans. Electron Devices 41, 2363 (1994)). We will show that graphene with a reduced degree of hydrogenation can compete, in terms of mobility, with silicon technology.

Two-dimensional semiconductors with possible high room temperature mobility (2014, methodology): “Bruzzone and Fiori used this Takagi model to compute the electron mobility of hydrogenated and fluorinated graphene as well as h-BCN from first principles [18] and show that graphene with a reduced degree of hydrogenation can compete with silicon technology.”
