Zusammenfassung

We have studied the transport properties of a semiconductor quantum dot with steep walls in the Coulomb blockade regime and under strong magnetic fields with a filling factor between 2 and 4 inside the dot. A striking periodic suppression of Coulomb blockade resonances as a function of gate voltage is found, which reflects the selective coupling of dot states that belong to different Landau ...
