DFT screened-exchange approach for investigating electronical properties of graphene-related materials
Roland Gillen, John Robertson
We present ab initio calculations of the bandstructure of graphene and of short zigzag graphene nanoribbons by the screened-exchange-LDA method (sX-LDA) within the framework of den…

Symmetry properties of vibrational modes in graphene nanoribbons
Roland Gillen, Marcel Mohr, Janina Maultzsch
We present symmetry properties of the lattice vibrations of graphene nanoribbons with pure armchair (AGNR) and zigzag edges (ZGNR). In non-symmorphic nanoribbons the phonon modes a…
