| 中文摘要 | the electronic structure of quantum rings is studied in the framework of the effective-mass theory and the two dimensional hard wall approximation. in cases of both the absence and presence of a magnetic field the electron momenta of confined states and the coulomb energies of two electrons are given as functions of the angular momentum, inner radius, and magnetic-field strength. by comparing with experiments it is found that the width of the real confinement potential is 14 nm, much smaller than the phenomenal width. the coulomb energy of two electrons is calculated as 11.1 mev. the quantum waveguide transport properties of aharonov-bohm (ab) rings are studied complementarily, and it is found that the correspondence of the positions of resonant peaks in ab rings and the momentum of confined states in closed rings is good for thin rings, representing a type of resonant tunneling. |
