FIG. 1.

Shallow-donor binding energies as functions of the barrier thickness in coupled quantum disks with a disk thickness of and a disk radius of in the absence of a magnetic field for the donor ion located at the center of the barrier. The solid curve is the results of the coupled quantum disks; the dashed curve is the result in Ref. 20.

FIG. 2.

Comparison of results for the binding energy of a hydrogenic-donor impurity in the coupled quantum disks for , , and with those of the double quantum well in Ref. 61. The donor ion is located at the center of the quantum disk.

FIG. 3.

Binding energy of a donor impurity as a function of the disk radius in symmetrical coupled quantum disks with , for , , and , for the case in which the donor ion is located at the disk center.

FIG. 4.

Binding energy of a donor ion as a function of the thickness of the disks in cylindrically symmetric coupled quantum disks with and , for (solid lines) and (dashed lines). The labels 1, 2, 3, and 4 correspond to the donor ion at the barrier center, barrier edge, disk center, and disk edge, respectively.
