Quantum Dots

Quantum Dots (QDs) are solid state structures made of semiconductors or metals that confine a countable, small number of electrons into a small space. As such they are often referred to as artificial atoms. The Klimeck group has modeled quantum dots extensively using the NEMO 3-D software.

There are a variety of journal and proceedings publications available. NEMO 3-D has been used to analyze quantum dots [P_2004_5, P_2004_11], alloyed quantum dots [J_2002_1, J_2003_1, P_2002_2, P_2003_1, P_2003_4], long range strain effects on quantum dots [J_2003_1, J_2003_3, J_2006_3, P_2003_4, P_2005_3, P_2005_6, P_2006_9], effects of wetting layers [J_2004_6, P_2004_4], piezo-electric effects in quantum dots [J_2007_13, P_2006_9, P_2007_1], quantum dot nuclear spin interactions [J_2005_1, P_2004_1, P_2004_5], quantum dot phonon spectra [J_2004_7, P_2004_3, P_2004_6], coupled quantum dot systems [J_2004_7, J_2006_3, P_2006_8],

The Quantum Dot Lab on nanoHUB.org is powered by NEMO 3-D and delivers very rapid simulations of simple quantum dots in a single band effective mass model. These simulations can be readily utilize to understand quantum dot principles.

This page serves as a simple entry page to some of the obtained simulation results, some quantum dot basics, and some interesting animations.
