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…
Raman spectroscopy and In-situ Raman spectroelectrochemistry of isotopically engineered graphene systems
Otakar Frank, Mildred S. Dresselhaus, Martin Kalbac
The unique properties of graphene offer immense opportunities for applications to many scientific fields, as well as societal needs, beyond our present imagination. One of the impo…
Strain Assessment in Graphene Through the Raman 2D' Mode
Elena del Corro, Ladislav Kavan, Martin Kalbac +1
Accurate and simple local strain assessment in graphene is one of the crucial tasks in device characterization. Raman spectroscopy is often used for that purpose through monitoring…
