英文摘要	The distribution of energy levels of the ground state and the low-lying excited states of hydrogenic impurities in inas quantum ring was investigated by applying the effective mass approximation and the perturbation method. in 2d polar coordinates, the exact solution to the schrodinger equation was used to calculate the perturbation integral in a parabolic confinement potential. the numerical results show that the energy levels of electron are sensitively dependent on the radius of the quantum ring and a minimum exists on account of the parabolic confinement potential. with decreasing the radius, the energy spacing between energy levels increases. the degenerate energy levels of the first excited state for hydrogenic impurities are not relieved, and when the degenerate energy levels are split and the energy spacing will increase with the increase in the radius. the energy spacing between energy levels of electron is also sensitively dependent on the angular frequency and will increase with the increases in it. the degenerate energy levels of the first excited state are not relieved. the degenerate energy levels of the second excited state are relieved partially. the change in angular frequency will have a profound effect upon the calculation of the energy levels of the ground state and the low-lying excited states of hydrogenic impurities in inas quantum ring. the conclusions of this paper will provide important guidance to investigating the optical transitions and spectral structures in quantum ring.
