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 SemiconductorStructureS in which the preSence or abSence of a quantum electron can be uSed to Store information. See alSo: quantum cell, quantum cell wire, {quantum-dot cellular automata}. . ["Quantum Dot HeteroStructureS", D. Bimberg, et al, John Wiley & SonS Ltd., Dec 1998]. (2001-07-17)
