Optical conductivity study of screening of many-body effects in graphene interfaces
Pranjal Kumar Gogoi, Iman Santoso, Surajit Saha +5
Theoretical studies have shown that electron-electron (e-e) and electron-hole (e-h) interactions play important roles in many observed quantum properties of graphene making this an…
Spatially resolved pump-probe study of single-layer graphene produced by chemical vapor deposition
Brian A. Ruzicka, Shui Wang, Jianwei Liu +3
Carrier dynamics in single-layer graphene grown by chemical vapor deposition (CVD) is studied using spatially and temporally resolved pump-probe spectroscopy by measuring both diff…
Large nonlinear Kerr effect in graphene
Han Zhang, Stephane Virally, Qiaoliang Bao +4
Under strong laser illumination, few-layer graphene exhibits both a transmittance increase due to saturable absorption and a nonlinear phase shift. Here, we unambiguously distingui…
