This theoretical/physics study analyzes the spectrum of electron-phonon complexes in monolayer graphene in a perpendicular quantizing magnetic field. It reports that near the threshold of optical phonon emission, standard perturbation theory fails for calculating the scattering amplitude. The authors describe new…

Jan 1, 2010
This paper presents a mesoscopic transport modeling framework (NEGF plus a real-space π-orbital model) to study how a uniform perpendicular magnetic field affects electronic transport in armchair graphene nanoribbons. The authors report width-dependent equilibrium current profiles and edge-localized transport under…
