Intermolecular contrast in atomic force microscopy images without intermolecular bonds
Sampsa K. Häm"aläinen, Nadine van der Heijden, Joost van der Lit +3
Intermolecular features in atomic force microscopy (AFM) images of organic molecules have been ascribed to intermolecular bonds. A recent theoretical study [P. Hapala et al., Phys.…
Epitaxial hexagonal boron nitride on Ir(111): A work function template
Fabian Schulz, Robert Drost, Sampsa K. Hämäläinen +3
Hexagonal boron nitride (h-BN) is a prominent member in the growing family of two-dimensional materials with potential applications ranging from being an atomically smooth support…
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…
Quantum confined electronic states in atomically well-defined graphene nanostructures
Sampsa Hämäläinen, Zhixiang Sun, Mark P. Boneschanscher +5
Despite the enormous interest in the properties of graphene and the potential of graphene nanostructures in electronic applications, the study of quantum confined states in atomica…
