Exotic Magnetic and Electronic Properties of Layered CrI3 Single Crystals Under High Pressure
Anirudha Ghosh, D. Singh, Qingge Mu +14
Through advanced experimental techniques on CrI single crystals, we derive a previously not discussed pressure-temperature phase diagram. We find that increases to $\…
Enhanced Raman Scattering on Functionalized Graphene Substrates
Václav Valeš, Petr Kovaříček, Michaela Fridrichová +5
The graphene-enhanced Raman scattering of Rhodamine 6G molecules on pristine, fluorinated and 4-nitrophenyl functionalized graphene substrates was studied. The uniformity of the Ra…
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…
Controlled oxygen plasma treatment of single-walled carbon nanotube films improves osteoblast cells attachment and enhances their proliferation
Marie Kalbacova, Antonin Broz, Alexander Kromka +2
The effects of oxidative treatment of single-walled carbon nanotubes (SWCNTs) on the adhesion and proliferation of human osteoblasts (SAOS-2) were investigated. The surface propert…
Towards quantification of the ratio of the single and double wall carbon nanotubes in their mixtures:An In situ Raman spectroelectrochemical study
Zuzana Kominkovaa, Vaclav Vales, Mark C. Hersam +1
Mixtures containing different weight ratios of single wall carbon nanotubes (SWCNT) and double wall carbon nanotubes (DWCNT) were prepared and studied by in-situ Raman spectroelect…
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…
Laser-ablation-assisted SF6 decomposition for extensive and controlled fluorination of graphene
Jan Plsek, Karolina Anna Drogowska, Michaela Fridrichov +2
We present a safe, clean, convenient, and easy-to-control method for extensive fluorination of graphene using laser-ablation-assisted decomposition of gaseous SF6 molecules.
Optical Near-Field Electron Microscopy
Raphaël Marchand, Radek Šachl, Martin Kalbáč +5
Imaging dynamical processes at interfaces and on the nanoscale is of great importance throughout science and technology. While light-optical imaging techniques often cannot provide…
Anomalous Freezing of Low Dimensional Water Confined in Graphene Nanowrinkles
Tim Verhagen, Jiri Klimes, Barbara Pacakova +2
Various properties of water are affected by confinement as the space-filling of the water molecules is very different from bulk water. In our study, we challenged the creation of a…
