Quantum Dots form such a system where the electron motion is constrained in all three spatial dimensions, similar to the case of regular atoms.
We are interested in the so called self-assembled quantum dots, which sometimes form spontaneously when different kinds of semiconductors are grown in thin layers. This phenomenon could potentially facilitate the fabrication of semiconductor structures where the motion of electrons can be controlled very precisely.
Our objective is to fabricate 3-D semiconductor quantum dot arrays with uniform spatial and size distribution, and to utilize large-scale computer simulations for experimental design and device fabrication.
