✦ Synopsis

Magneto-optical properties and resonant Raman spectroscopy of modulation doped GaAs-AlGaAs quantum well wires are reported. Their properties are compared with similar undoped quantum well wires to investigate the many electron effects in nanostructures. In undoped samples, the quantised energy levels observed by luminescence excitation spectroscopy are in good agreement with a particle-in-a-box model. In doped samples, the carrier confinement is explicitly revealed by magnetoluminescence and depolarised resonant Raman scattering. The calculated spectra in a Hartree model are in reasonable agreement with experiment.
