Magnetic field sensitivity of the coulomb anomaly in the conductance of phase-coherent disordered 2-idmensional electron gas
We have studied the Coulomb anomaly in the conductance of a phase-coherent disordered 2-dimensional electron gas. Its average magnitude ofδG{sub}EEI≈ 0.3 e{sup}2/h is obtained by applying a bias voltage to suppress the Coulomb anomaly. ThisCoulomb anomaly is suppressed by a parallel magnetic field in contrast to theoretical predictions. Surprisingly, the magnitude of this Coulomb anomaly exhibits reproducible fluctuations in perpendicular magnetic fields on a magnetic field scale muchlarger than that for universal conductance fluctuations.
