The quantum effects of magnetic flux and in-plane electric field on an electron in a two-dimensional double-barrier nano-ring 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.
