quantum dot
noun
: a semiconductor nanocrystal exhibiting quantum mechanical effects that allow it to mimic the properties of an atom
The quantum dot is a semiconducting (or metallic) region so tiny that it is essentially confined in all three dimensions; like an atom, it contains a finite number of charges and has discrete energy levels.—
