| 中文摘要 | in the framework of effective mass envelope function theory, the electronic states of the inas/gaas quantum ring are studied. our model can be used to calculate the electronic states of quantum wells, quantum wires, and quantum dots. in calculations, the effects due to the different effective masses of electrons in rings and out rings are included. the energy levels of the electron are calculated in the different shapes of rings. the results indicate that the inner radius of rings sensitively changes the electronic states. the energy levels of the electron are not sensitively dependent on the outer radius for large rings. if decreasing the inner and outer radii simultaneously, one may increase the energy spacing between energy levels and keep the ground state energy level unchanged. if changing one of two radii (inner or outer radius), the ground state energy level and the energy spacing will change simultaneously. these results are useful for designing and fabricating the double colors detector by intraband and interband translations. the single electron states are useful for studying the electron correlations and the effects of magnetic fields in quantum rings. our calculated results are consistent with the recent experimental data of nanoscopic semiconductor rings.
