NEGATIVE DONOR CENTER QUANTUM DOTS IN MAGNETIC FIELDS

The method of few-body physics is applied to treat a D^- center quantum dot system in a magnetic field. The magnetic field is applied in the z direction. Using this method, we investigate the energy spectra of low-lying states of D^- center quantum dots as a function of magnetic field. The dependence of the binding energies of the ground-state of the D^- center are calculated as a function of the dot radius with a few values of the magnetic field strength and compared with other results.
