Magneto: transporte dissipativo não linear no grafeno em regime de efeito Hall quântico devido à interação elétron-fônon

Abstract

In the present dissertation studied the effect of a uniform electric field , applied the Over a graphene layer , On the spectrum of Landau levels. We calculate one Current Density dissipative Until Monday constant of the Order of electron phonon interaction Para um system composed of a two-dimensional electron gas interacting with acoustic phonons in graphene One Network, In Effect conditions Quantum Hall in hum finite electric field. Show que ONLY real energy transitions contribute Pará Chain dissipative . Also we calculate one Hall of the system conductivity, paragraph a Wed. retrieve a known expression M = 4 ( N + 1 = 2 ) = e 2 h .
