Description

Quantum Dot Lab is a nanoHUB simulaton tool. It computes the eigenstates of a particle in a box of various shapes including domes, pyramids and multilayer structures.

This educational tool simulates particle in a box problem for a variety of geometries such as boxes, cylinders, pyramids, and ellipsoids and multilayer structures composed of substrate, wetting layer, quantum dot and capping layer. Users can choose between simple single band effective mass model, two band effective mass model and 10 band sp3d5s* tight binding model (with spin-orbit coupling) and run interactively. 3-D visualization depicts the 3-D confined wave functions.
