“Paramagnetic adsorbates on graphene: a charge transfer analysis”. Leenaerts O, Partoens B, Peeters FM, Applied physics letters 92, 243125 (2008). http://doi.org/10.1063/1.2949753
Abstract: We introduce a modified version of the Hirshfeld charge analysis method and demonstrate its accurateness by calculating the charge transfer between the paramagnetic molecule NO2 and graphene. The charge transfer between paramagnetic molecules and a graphene layer as calculated with ab initio methods can crucially depend on the size of the supercell used in the calculation. This has important consequences for adsorption studies involving paramagnetic molecules such as NO2 physisorbed on graphene or on carbon nanotubes. © 2008 American Institute of Physics.

“Tunable double Dirac cone spectrum in bilayer \alpha-graphyne”. Leenaerts O, Partoens B, Peeters FM, Applied physics letters 103, 013105 (2013). http://doi.org/10.1063/1.4812977
Abstract: Monolayer alpha-graphyne was recently proposed as a new all-carbon material having an electronic spectrum consisting of Dirac cones. Based on a first-principles investigation of bilayer alpha-graphyne, we show that the electronic band structure is qualitatively different from its monolayer form and depends crucially on the stacking mode of the two layers. Two stable stacking modes are found: a configuration with a gapless parabolic band structure, similar to AB stacked bilayer graphene, and another one which exhibits a doubled Dirac-cone spectrum. The latter can be tuned by an electric field with a gap opening rate of 0.3 eA. (C) 2013 AIP Publishing LLC.

“Vibrational properties of graphene fluoride and graphane”. Peelaers H, Hernández-Nieves AD, Leenaerts O, Partoens B, Peeters FM, Applied physics letters 98, 051914 (2011). http://doi.org/10.1063/1.3551712
Abstract: The vibrational properties of graphene fluoride and graphane are studied using ab initio calculations. We find that both sp(3) bonded derivatives of graphene have different phonon dispersion relations and phonon densities of states as expected from the different masses associated with the attached atoms of fluorine and hydrogen, respectively. These differences manifest themselves in the predicted temperature behavior of the constant-volume specific heat of both compounds. (C) 2011 American Institute of Physics. [doi:10.1063/1.3551712]
