Abstract: | Using the method of numerical matrix diagonalization within the effective-mass approximation, we investigated a
D--center quantum dot system subjected to a Gaussian potential
confinement. We obtain the dependence of binding energies of the
ground-states of the
D--center on the depth of Gaussian potential and the magnetic field strength. The result shows
clearly that the binding energies of the ground-states of the
D--center are rather sensitive to the depth of potential and
the strength of magnetic field. |
