Experimental realization of a Fabry-Perot-type interferometer by co-propagating edge states in the quantum Hall regime

Published 2007-12-10, updated 2008-03-18Version 2

A Fabry-Perot-type interferometer is experimentally realized for electrons in a semiconductor device. A special experimental geometry creates interference conditions for co-propagating electrons in quantum Hall edge states, which results in oscillations of the current through the device. The visibility of these oscillations is found to increase at the high-field edge of the quantum Hall plateau.
