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 earlier works, become invisible for relatively small source–drain voltages, as the current decays rapidly with magnetic field. Quantum interference still governs the behaviour of higher charge-transfer cumulants.
