Model of a GaAs Quantum Dot in a Direct Band Gap AlGaAs Wurtzite Nanowire

Abstract

We present a study with a numerical model based on (Formula presented.), including electromechanical fields, to evaluate the electromechanical and optoelectronic properties of single GaAs quantum dots embedded in direct band gap AlGaAs nanowires. The geometry and the dimensions of the quantum dots, in particular the thickness, are obtained from experimental data measured by our group. We also present a comparison between the experimental and numerically calculated spectra to support the validity of our model.
