Non-linear optical properties of InGaAs/AlGaAs nanostructures grown on (N11) surfaces

摘要

We report on experimental and theoretical study of GaA/InGaAs quantum systems grown along the [N11] direction. Time-resolved photoluminescence measurements have revealed a strong non-linear optical response from a sidewall quantum wire. The experimental results were reproduced by theoretical calculations taking into account strain, piezo-charge and excitonic effect. Also we theoretically investigated the effect of strain and piezo-charge on the properties of a quantum dot.
