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…
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…
Strong Localization Effects in the Photoluminescence of Transition Metal Dichalcogenide Heterobilayers
Alvaro Rodriguez, Martin Kalbac, Otakar Frank
The emergence of various exciton-related effects in transition metal dichalcogenides (TMDC) and their heterostructures has inspired a significant number of studies and brought fort…
Imaging Nanoscale Inhomogeneities and Edge Delamination in As-Grown MoS2 Using Tip-Enhanced Photoluminescence
Alvaro Rodriguez, Tim Verhagen, Martin Kalbac +2
Methods for nanoscale material characterization are in ever-increasing demand, especially those that can provide a broader range of information at once. Near-field techniques based…
