Mono-Mono-Mono and Bi-Bi-Bi three-layer graphene systems’ optical conductivity

Investigating the longitudinal optical conductivity of graphene systems, which is the mostimportant property for opto-electronic devices, for three-layer graphene systems theoretically and numerically is the main purpose of this study. Each layer can be mono- or bi-layer graphene. Separation between layers has been denoted by d, selected to be about ten nanometers. The carrier densities i...

Evidence for a spin phase transition at charge neutrality in bilayer graphene

The quantum spin Hall effect is characterized by spin-polarized counter-propagating edge states1–3. It has been predicted that this edge state configuration could occur in graphene when spin-split electronand hole-like Landau levels are forced to cross at the edge of the sample4–6. In particular, a quantumspin-Hall analogue has been predicted in bilayer graphene with a Landau level filling fact...
