quantum dot

(physics)
(Or "single-electron transistor") A location capable of containing a single electrical charge; i.e., a single electron of Coulomb charge. Physically, quantum dots are nanometer-size semiconductor structures in which the presence or absence of a quantum electron can be used to store information.
