Abstract

Quantum dots (QDs) realized by etching or gate structures in a two-dimensional electron system may, under realistic conditions, contain an impurity atom which causes deviations of the electron structure from the ideal case. We have performed ground-state calculations for circular disk-like QDs with a parabolic confinement potential and a repulsive off-center impurity. Besides the distance of the ...
