Drift response to a high electric field in graphene and carbon nanotubes (CNTs) is delineated using nonequilibrium Arora distribution function (NEADF), a paradigm that is distinctly different from that using the nonequilirium Green function and other theoretical paradigms. In this formalism, the re-organization of randomly oriented velocity vectors is shown to streamline and become unidirectional...
Summary form only given. Ballistic transport is collision-free carriers drift in a conducting channel whose ballistic length LB is smaller than the scattering-limited mean free path ℓB. In such channels, the probability of scattering is still finite. The probability that a carrier after being injected from the Ohmic contacts will undergo collision in traversing a ballistic length LB is exp(-LB / ℓ...
