Quantum-limited shot noise and quantum interference in graphene based Corbino disk
arXiv:1401.7247 · doi:10.1080/14786435.2014.974712
Abstract
This is a theoretical study of finite voltage effects on the conductance, the shot noise power, and the third charge-transfer cumulant for graphene-based Corbino disk in the presence of external magnetic fields. Periodic magnetoconductance oscillations, predicted in Refs. [1,2], become invisible for relatively small source-drain voltages, as the current decays rapidly with magnetic field. Quantum interference still governs the behavior of higher charge-transfer cumulants.
