Temperature dependence of the visibility in an electronic Mach-Zehnder interferometer
arXiv:1004.1945 · doi:10.1016/j.physe.2009.11.072
Abstract
We performed the conductance and the shot noise measurements in an electronic Mach-Zehnder interferometer. The visibility of the interference is investigated as a function of the electron temperature that is derived from the thermal noise of the interferometer. The non-equilibrium noise displays both h/e and h/2e oscillations vs. the modulation gate voltage.
