We carried out micro-photoluminescence studies of doped multiple quantum wire structures grown by the cleaved-edge overgrowth technique in the GaAs/AlGaAs material system. The wires are defined in a quantum well whose potential is modulated by adjacent alternating negatively and positively charged layers. We observed strong band gap renormalization effects in the quantum wires indicating that ...
