The Structure and Local Variations of the Graphene Moiré on Ir(111)
Sampsa K. Hämäläinen, Mark P. Boneschanscher, Peter H. Jacobse +6
We have studied the incommensurate moiré structure of epitaxial graphene grown on iridium(111) by dynamic low energy electron diffraction [LEED-I(V)] and non-contact atomic force m…
Structural manipulation of the graphene/metal-interface with Ar+ irradiation
E. H. Åhlgren, S. K. Hämäläinen, O. Lehtinen +2
Controlled defect creation is a prerequisite for the detailed study of disorder effects in materials. Here, we irradiate a graphene/Ir(111)-interface with low-energy Ar+ to study t…
Electronic states in finite graphene nanoribbons: Effect of charging and defects
M. Ijäs, M. Ervasti, A. Uppstu +4
We study the electronic structure of finite armchair graphene nanoribbons using density-functional theory and the Hubbard model, concentrating on the states localized at the zigzag…
