Abstract:
We have performed photoluminescence experiments on modulated barrier In 0.13 Ga 0.87 As/GaAs quantum wires in normal magnetic fields up to B = 10.5 T. By using high excitation powers we observed emission from several lateral subbands. In comparison to low excitation spectra the emission features are shifted to lower energies due to band gap renormalization. Calculated luminescence spectra are in excellent agreement with the experimental spectra and have been used to study many-particle effects in these wires. We have found clear indications for an enhancement of the renormalization in quantum wires as expected due to the increase of the Coulomb interaction.
