Abstract

We study the visibility of Aharonov-Bohm interference in an electronic Mach-Zehnder interferometer in the integer quantum Hall regime. The visibility is controlled by the filling factor nu and is observed only between nu[approximate]2.0 and 1.0, with an unexpected maximum near nu=1.5. Three energy scales extracted from the temperature and voltage dependences of the visibility change in a very ...
