▎ 摘  要

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.
