Abstract
Quantum dots can be produced in a variety of material systems and geometries.
The simulations are performed with NEMO5 which can handle realistically extended quantum dot systems for exploration purposes.
The default simple geometries such as boxes, cylinders, pyramids, and ellipsoids enable educational users to explore confinement symmetries and absorption experiments in one conduction band.
3-D visualization depicts the 3-D confined wave functions. Optical transitions are computed and sorted into dark and light lines. Absorption curves are computed for different polarizations and orientations. Parameters such as incident light angle and polarization, Fermi level, or temperature can be scanned to analyze the effect of 3-D geometries on isotropic optical properties.
