摘要：
This letter presents the experimental demonstration of a Coulomb blockade (CB) logic device. Our logic architecture consists of an array of current pathways, controlled by CB switching nodes. In this architecture, high gain is not required to transmit information, making it well suited to the CB device. Each CB node is switched between a blockaded state and a completely pinched-off state, minimizing the influence of stray potentials. Using a multi-phase clocking scheme to precisely control electron flow, the AND logic function is observed using as few as 160 electrons. (C) 1998 American Institute of Physics.
