Interdiffusion of Al and Ga at the GaAs/AlGaAs heterointerface is enhanced by focused Ga ion beam implantation and subsequent annealing. Quantum well wire structures are fabricated using this interdiffusion enhancement resulting from focused Ga ion beam raster scanning. Fabricated structures reveal multiple fine structures in their low temperature photoluminescence and its excitation spectra. These multiple fine structures are considered to originate from the density of states specific to one-dimensional carrier systems.
