Calculation of optical properties of a quantum dot embedded in a GaN/AlGaN nanocolumn

The TiberCAD simulation tool for calculation of optical and electronic properties of nanostructured devices has been used to study spontaneous emission of a GaN quantum dot embedded in an AlGaN nanocolumn. Macroscopic calculations provide corrections to the quantum calculation, showing the role of strain and the polarization field in spectra and the electron and hole states arrangement.
