中文摘要	in this paper, we propose the periodic boundary condition which can be applied to a variety of semiconductor nanostructures to overcome che difficulty of solving schrodinger equation under the natural boundary condition. when the barrier width is large enough. the average of the maximum and minimum of energy band under the periodic boundary condition is very close to the energy level obtained under the natural boundary condition. as an example, we take the gaas/ga1-xalxas system, if the width of the ga1-xalxas barrier is 200 angstrom, the average of the maximum and minimum of energy band of the gaas/ga1-xalxas superlattices is very close to the energy level of the gaas/ga1-xalxas quantum wells (qws). we give the electronic structure effective mass calculation of t-shaped quantum wires (t-qwrs) under the periodic boundary condition, the lateral confinement energies e1d-2d of electrons and holes, the energy difference between t-qwrs and qws, are precisely determined.
