Quantum dot
A quantum dot is a semiconductor whose excitons are confined in all three spatial dimensions. Consequently, such materials have electronic properties intermediate between those of bulk semiconductors and those of discrete molecules.
Excitons in Si nanoparticles. In bulk Si these excitons quickly recombine however in nanoparticles one exciton can remain to exist for some time. It is possible to put these nanoparticles together in which these excitons, each in their own nanoparticle, have interaction with eachother.
