Probing the Local Dielectric Function by Near Field Optical Microscopy Operating in the Visible Spectral Range
Oisín Garrity, Alvaro Rodriguez, Niclas S. Mueller +2
The optoelectronic properties of nanoscale systems such as carbon nanotubes (CNTs), graphene nanoribbons and transition metal dichalcogenides (TMDCs) are determined by their dielec…
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…
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…
