Abstract

We have considered a two dimensional narrow semiconductor ring with sectorial barriers that is threaded by magnetic flux. Using numerical diagonalization techniques, we have presented the diagrams of the energy spectra versus the magnetic flux. For a constant value of the barrier height, with enhancement of the number of barriers, the energy levels shift to higher energies and the degeneracy of the system increases. We have also investigated the behavior of the energy levels with the magnetic flux for different values of the barrier height. The fluctuation of the energy levels decreases, as the barriers' height increases.
