Phys. Rev. B 80, 153401 (2009) [4 pages]Aharonov-Bohm oscillations in the local density of statesReceived 16 June 2009; revised 18 August 2009; published 1 October 2009 The scattering of electrons with inhomogeneities produces modulations in the local density of states of a metal. We show that electron interference contributions to these modulations are affected by the magnetic field via the Aharonov-Bohm effect. This can be exploited in a simple scanning-tunneling-microscopy setup that serves as an Aharonov-Bohm interferometer at the nanometer scale. © 2009 The American Physical Society URL:
