We propose an original method to fabricate one-dimensional (1D) semiconductor nanostructures using dislocations, generated by plastic deformation, as atomic scale saws to cut a 2D-structure into a multiple quantum wire structure. The 2D-structure used to apply this method is a 5 nm GaAs/GaAlAs quantum well grown by molecular beam epitaxy on a (001) GaAs substrate.The photoluminescence (PL) spectrum...
