Collective modes in anisotropic double layer systems
A. S. Rodin, A. H. Castro Neto
We study collective modes in anisotropic double layer systems. To this end, we derive a zero- dynamic polarization function for a conductor with a paraboloidal dispersion. Follo…
Exciton binding energies and luminescence of phosphorene under pressure
L. Seixas, A. S. Rodin, A. Carvalho +1
The optical response of phosphorene can be gradually changed by application of moderate uniaxial compression, as the material undergoes the transition into an indirect gap semicond…
Phosphorene nanoribbons
A. Carvalho, A. S. Rodin, A. H. Castro Neto
Edge-induced gap states in finite phosphorene layers are examined using analytical models and density functional theory. The nature of such gap states depends on the direction of t…
Ultrafast and Nanoscale Plasmonic Phenomena in Exfoliated Graphene Revealed by Infrared Pump-Probe Nanoscopy
Martin Wagner, Zhe Fei, Alexander S. McLeod +14
Pump-probe spectroscopy is central for exploring ultrafast dynamics of fundamental excitations, collective modes and energy transfer processes. Typically carried out using conventi…
