Abstract

Local density distribution of electronic states confined in a two-dimensional ring structure under a magnetic field is calculated. Surface two-dimensional electron system, such as the Cu(111) surface states, is assumed as the original states in the calculation. A simulated image of scanning tunneling microscope (STM) shows periodical changes in its pattern with a magnetic field passing through the ring, corresponding to the Aharanov-Bohm effect. Optimised experimental conditions for its practical STM observation are discussed.
