摘要：

The quantum effects of magnetic flux and in-plane electric field on an electron in a two-dimensional double-barrier nanoring have been studied. It has been found that the electronic structures and the related properties in the ring, such as the polarization, persistent currents, and far-infrared spectroscopy, can be tailored and controlled by the double barriers and the electric field. It may be useful for applications in quantum devices design in the future. (C) 2003 American Institute of Physics.
