Aharonov-Bohm oscillations in the Coulomb blockade regime

Abstract

We discuss the electronic transmission through lateral dots, featuring both the Aharonov-Bohm-type oscillations observed in high magnetic field sweeps and Coulomb blockade oscillations detected as a function of electron density. We focus on the interplay of these two effects and demonstrate two intrinsic features of submicron dot behavior---the manifestation of the Aharonov-Bohn oscillations in a resonant reflection mode and a novel regime characterized by the simultaneous observation and a commensurate relationship of the two effects.
