Popis: We have developed InGaAs/GaAs wires by using the lateral modulation of the top barrier material of the quantum well substrates to obtain a lateral confinement. Our approach provides buried wires without the creation of defects in the active regions. Therefore we obtain high quantum efficiencies from wires with lateral dimensions down to 35 nm.
