SIcs> (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.
