Abstract

demo

Quantum dots can be produced in a variety of material systems and geometries. This simple educational tool simulates the particle in a box problem for a variety of geometries such as boxes, cylinders, pyramids, and ellipsoids. A simple single band effective mass model is employed and the simulations run interactively. 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.

This tool is supported by a tutorial lecture and a set of homework and project exercises.
