2D-1D crossover from quantum well to quantum wire behaviour in GaAs v-groove structures
he distribution of electron current in GaAs AlGaAs v-groove quantum wire structures with groove widths varying from 1 to 25 mum has been studied using far- and near-field spectroscopy techniques. We find clear evidence of the formation of 'corner' quantum wires in wide grooves which coales...
