Excited states of ring-shaped (InGa)As quantum dots in a GaAs∕(AlGa)As quantum well

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 g...
