Description
Summary:碩士 === 國立成功大學 === 物理學系碩博士班 === 98 === In this thesis, a model of radial infinite square well is considered to simulate the self-assembled semiconductor single quantum ring and double rings. By using the exact solutions of the single quantum ring, one can expand the Hamiltonian function of electron or hole in single quantum ring and double rings and obtain the eigen-energies and eigen-functions numerically. Aharonov-Bohm effect is found to exist in both of the two cases under the exterior uniform magnetic field. In addition, we also study the energy spectra in the presence of spin-orbit interaction. It is found that the periodic oscillation of AB effect can be degraded seriously by the spin-orbit interaction.
