Potential Energy Landscape for hot electrons in periodically nanostructured graphene
arXiv:1004.0593 · doi:10.1103/PhysRevLett.105.036804
Abstract
We explore the spatial variations of the unoccupied electronic states of graphene epitaxially grown on Ru(0001) and observed three unexpected features: the first graphene image state is split in energy, unlike all other image states, the split state does not follow the local work function modulation, and a new interfacial state at +3 eV appears on some areas of the surface. These results show the system behaves as a self-organized periodic array of quantum dots.
