中文摘要	quantum-confined stark effects are investigated theoretically in gaas/alxga1-xas quantum wires formed in v-grooved structures. the electronic structures of the v-shaped quantum wires are calculated within the effective mass envelope function theory in the presence of electric field. the binding energies of excitons are also studied by two-dimensional fourier transformation and variational method. the blue stark shifts are found when the electric field is applied in the growth direction. a possible mechanism in which the blueshifts of photoluminescence peaks are attributed to two factors, one factor comes from the asymmetric structure of quantum wire along the electric field and another factor arises from the electric-field-induced change of the coulomb interaction. the numerical results are compared with the recent experiment measurement.
