Graphene on graphene antidot lattices: Electronic and transport properties
Søren Schou Gregersen, Jesper Goor Pedersen, Stephen R. Power +1
Graphene bilayer systems are known to exhibit a band gap when the layer symmetry is broken, by applying a perpendicular electric field. The resulting band structure resembles that…
Electronic transport in disordered graphene antidot lattice devices
Stephen R. Power, Antti-Pekka Jauho
Nanostructuring of graphene is in part motivated by the requirement to open a gap in the electronic band structure. In particular, a periodically perforated graphene sheet in the f…
RKKY interaction between extended magnetic defect lines in graphene
Paul D. Gorman, John M. Duffy, Stephen R. Power +1
Of fundamental interest in the field of spintronics is the mechanism of indirect exchange coupling between magnetic impurities embedded in metallic hosts. A range of physical featu…
Sublattice imbalance of substitutionally doped nitrogen in graphene
James A. Lawlor, Paul D. Gorman, Stephen R. Power +2
Motivated by the recently observed sublattice asymmetry of substitutional nitrogen impurities in CVD grown graphene, we show, in a mathematically transparent manner, that oscillati…
Dual-probe spectroscopic fingerprints of defects in graphene
Mikkel Settnes, Stephen R. Power, Dirch H. Petersen +1
Recent advances in experimental techniques emphasize the usefulness of multiple scanning probe techniques when analyzing nanoscale samples. Here, we analyze theoretically dual-prob…
Theoretical analysis of a dual-probe scanning tunneling microscope setup on graphene
Mikkel Settnes, Stephen R. Power, Dirch H. Petersen +1
Experimental advances allow for the inclusion of multiple probes to measure the transport properties of a sample surface. We develop a theory of dual-probe scanning tunnelling micr…
