Abstract

We have measured photon-assisted tunneling through a quantum dot with zero dimensional (0D) states. For photon energies smaller than the separation between 0D states we observe photon sideband resonances of the ground state. When the photon energy exceeds the separation between 0D states we observe photon-induced excited state resonances. We identify the different resonances by studying their dependence on photon frequency and magnetic field.
