Addressing Raman features of individual layers in isotopically labeled Bernal stacked bilayer graphene
Sara D Costa, Johan Ek Weis, Otakar Frank +2
The most important bands for the evaluation of strain in graphene (the 2D and 2D prime modes) are investigated. It is shown that for Bernal-stacked bilayers, the two-phonon Raman f…
Temperature and Face Dependent Copper-Graphene Interactions
Sara D. Costa, Johan Ek Weis, Otakar Frank +1
The interaction between graphene and metals represents an important issue for the large-area preparation of graphene, graphene transfer and the contact quality in graphene devices.…
Effect of layer number and layer stacking registry on the formation and quantification of defects in graphene
Sara D. Costa, Johan Ek Weis, Otakar Frank +1
Correct defect quantification in graphene samples is crucial both for fundamental and applied re-search. Raman spectroscopy represents the most widely used tool to identify defects…
Non-trivial topological valence bands of common diamond and zinc-blende semiconductors
Tomáš Rauch, Victor A. Rogalev, Maximilian Bauernfeind +11
The diamond and zinc-blende semiconductors are well-known and have been widely studied for decades. Yet, their electronic structure still surprises with unexpected topological prop…
