Abstract

We present simulation results obtained using a 3D coupled Schrodinger-Poisson equation solver. Of special interest in this work were the effects that discrete impurities have on the energy spectra in the dot and how these effects can be used to better explain conductance peaks observed in experimental measurements. We also explored the behavior of the energy level separations in the closed quantum dot system, observing indications of the onset of chaos.
