Exciton in a quantum wire in the presence of parallel and perpendicular magnetic fields

The exciton properties of self-assembled rectangular and V-shaped quantum wires are investigated theoretically in the presence of a magnetic field. The calculations are done in the single band effective mass approximation. We study the diamagnetic shift, the influence of the electron-hole Coulomb interaction, as well as the electronic properties and the photoluminescence peak energies for magnetic fields applied along and perpendicular to the wire. The results are compared with available magneto-photoluminescence experimental measurements.
