Interdiffusion induced enhancement of one-dimensional level separation in quantum wires

Interdiffusion induced enhancement of one-dimensional level separation in quantum wires

We have calculated the effect of alloy interdiffusion on the one-dimensional energy confinement of (Al,Ga)As/GaAs crescent shaped quantum wire structures. We show that the energy splitting between excited states may be greatly enhanced by the interdiffusion mechanism.
