Giant quasiparticle bandgap modulation in graphene nanoribbons supported on weakly interacting surfaces

Xueping Jiang, Neerav Kharche, and Paul Kohl et al.

In general, there are two major factors affecting bandgaps in nanostructures: (i) the enhanced electron-electron interactions due to confinement and (ii) the modified self-energy of electrons due to the dielectric screening. While recent theoretical studies on graphene nanoribbons (GNRs) report on ... [Appl. Phys. Lett. 103, 133107 (2013)] published Wed Sep 25, 2013.
