Abstract
The ground-state property of a two-dimensional three-electron quantum dot subjected to an external magnetic field and affected by an impurity is studied. The impurity is located at the axis by a distance from the plane of the dot. The evolution of the angular momentum and the total spin of the ground states in accord with and has been calculated, and is visualized in a phase diagram. The physics underlying this diagram has been analyzed.
