Nonequilibrium Excitations and Transport of Dirac Electrons in Electric-Field-Driven Graphene

20 May 2018 Li Jiajun Han Jong E.

We investigate nonequilibrium excitations and charge transport in charge-neutral graphene driven with DC electric field by using the nonequilibrium Green's function technique. Due to the vanishing Fermi surface, electrons are subject to non-trivial nonequilibrium excitations such as highly anisotropic momentum distribution of electron-hole pairs, an analog of the Schwinger effect...
