Abstract :
GaAs quantum wires are naturally formed by MBE on vicinal GaAs(110) surfaces with coherently aligned giant growth steps due to thickness modulation at step edges. Two-step growth with growth interruption is employed to improve uniformity and confinement energies of quantum wires, which are confirmed by photo and cathodoluminescence measurements.
