Abstract: By studying the resonant tunneling of electrons through self-assembled ring-shaped (InGa)As quantum dots embedded in the quantum well of an (AlGa)As/GaAs/ (AlGa)As heterostructure, we find evidence for the existence of excited states of the quantum dots which exhibit a 2pz-like character along the growth direction z. The states are investigated by magnetotunneling spectroscopy with magnetic fields applied parallel and perpendicular to z.
