摘要：
The method of few-body physics is applied to calculate the low-lying states of the exciton of a GaAs disk-like quantum dot with a parabolic potential. The binding energy of the exciton in quantum disks is calculated for two different thickness as a function of the quantum-disk radius. The four lowest exciton levels on dependence of the disk thickness is investigated. (C) 2000 Elsevier Science B.V. All rights reserved.
