    Quantum Dots: Building Blocks of Quantum Devices?

    Among other systems quantum dots have been considered as one of the prime candidates for a solid state quantum information processing that is scalable up to a large number of quantum bits. After some general ...

    Microcavities with 3D Optical Confinement

    We have fabricated microcavities with three-dimensional optical confinement by the combination of epitaxially grown vertical cavity surface emitting cavity structures and lithographic patterning. The emission ...

    Optical Investigation of Coupled GaAs/Al0.3Ga0.7As Double Quantum Wells Separated by AIAs Barriers

    Electronically symmetric coupled double quantum wells are structures where two quantum wells are separated by a thin barrier layer. Both experiment and theory show that when the barrier is so narrow that there...

    Bevel fabrication for depth resolved studies of multiple quantum well structures

    Beveled cross-sections of semiconductors with inclination angles down to 0.25 min of arc have been produced with a special ion beam etching process. We applied this technique to the depth resolved characteriza...
