โœฆ Synopsis

We calculate the excitonic transition energy in T-shaped quantum well wires. Th.: complexity of the valence band is taken into account. This leads to a description of the exciton where the hole is bound mainly to the electron when the wire valence band confinement potential is too weak. This allows one a comparison with experimental results obtained in Gal _.,.AliAs T-shaped quantum well wires with widths of 70 and 50A and x=0.3 and 0.35.

We determine the exciton states of T-shaped quantum wires. We use anisotropic effectivemass models to describe the electron and hole states. Pair correlation along the wire axis and in the lateral directions is included. We accurately model the measured redshifts between exciton photoluminescence in
