摘要：

We calculate the spatial distribution of the electron density and the dispersion curves of the subband structure for the quantum wire patterned from the GaAs/AlGaAs heterostructure within the framework of the Hartree-Fock approximation. It is shown that electrons move to the part underneath the modulation-doped layer as the strength of the Coulomb interaction is increased, and that the pattern behaviour of the dispersion curve below the Fermi energy depends strongly on the strength of the Coulomb interaction and on the total electron number.
