Abstract

Binding energies and wave functions are calculated for the ground-state exciton in T-shaped quantum wires. It is shown that, if Coulomb interaction is taken into account, the hole is strongly localized by correlation with the electron. We demonstrate that no one-dimensional hole confinement is necessary for the formation of a one-dimensional exciton and that the exciton is roughly described by a ...
