| Abstract(in English) | We demonstrate both numerically and experimentally that time-controlled single-electron transfer can be achieved in single-gated systems with random multiple-tunnel-junctions (MTJ). Charge transfer is controlled by a ratchet-like free energy landscape which can be achieved with higher probability in random systems even if only one gate controls the potential in all the Coulomb islands. We confirm this behavior analytically through Monte Carlo simulations based on the orthodox theory of Coulomb blockade. Furthermore, we investigate the operation of Si nanowire field-effect transistors with several phosphorous impurities implanted in the channel. We show that the doping process leads to splitting the channel into a ID multiple-tunnel-junction array with naturally introduced parameter randomness. We report here the first experimental observation of time-controlled single-electron transfer achieved in ID MTJ arrays created by phosphorous dopants and suggest the importance of phosphorous for future Coulomb blockade device applications. |
