Dielectric Screening Inside Carbon Nanotubes
Georgy Gordeev, Sören Wasserroth, Han Li +3
Dielectric screening plays a vital role for the physical properties in the nanoscale and also alters our ability to detect and characterize nanomaterials by optical techniques. We…
Moiré-induced Vibrational Coupling in Double Walled Carbon Nanotubes
Georgy Gordeev, Sören Wasserroth, Han Li +2
Moiré patterns are additional, long-range periodicities in twisted crystalline bilayers. They are known to fundamentally change the electronic states of the layers, but similar eff…
Electronic band gaps of confined linear carbon chains ranging from polyyne to carbyne
Lei Shi, Philip Rohringer, Marius Wanko +7
Ultra long linear carbon chains of more than 6000 carbon atoms have recently been synthesized within double-walled carbon nanotubes, and they show a promising new route to one--ato…
Evaluating arbitrary strain configurations and doping in graphene with Raman spectroscopy
Niclas S. Mueller, Sebastian Heeg, Miriam Peña Alvarez +13
Raman spectroscopy is a powerful tool for characterizing the local properties of graphene. Here, we introduce a method for evaluating unknown strain configurations and simultaneous…
Quantum Nature of Plasmon-Enhanced Raman Scattering
Patryk Kusch, Sebastian Heeg, Christian Lehmann +6
We report plasmon-enhanced Raman scattering in graphene coupled to a single plasmonic hotspot measured as a function of laser energy. The enhancement profiles of the G peak show st…
