In this paper, we studied four-electron systems confined in one-, two-, and four-layer quantum dots, by the exact diagonalization method. A vertical magnetic field to the confinement plane is considered. The ground-state electronic structures and the spin and angular momentum transitions for different magnetic fields are investigated. Series of magic numbers of angular momentum which minimize the ground-state electron–electron interaction energy have been discovered. These are connected to the exchange and rotational symmetries of the systems.

Energy Band Offset

The electronic structures of CdSe/CdxZn1-xS core/shell quantum dots are investigated systematically using the effective-mass approximation method. The calculated results have shown that both of the electron and hole are completely localized at the range of core, which can be ascribed to the large energy band offset in valence band and conduction band. The carriers appear in the region of core or shell, which mainly depend on the competition between the kinetic energy and the potential energy in the heterostrucuture QDs. The transition energies can be widely tuned by the changing the structure parameters.
