Abstract
We have investigated Coulomb blockade oscillations in a quantum dot with two confined Landau levels. Some oscillations show switching between two discrete conductance values as a function of time. We show that these switches are due to single electron tunnel events between the two Landau levels. Upon increasing the magnetic field, we find that the time between two tunnel events reaches macroscopic values on the order of 100 s.Keywords
