Abstrakt: A single-electron-tunneling (SET) device with variable environmental impedance is investigated. A self-consistent numerical calculation shows that the resistive environmental impedance can control the SET device. It is experimentally observed that the Coulomb gap becomes wider as the resistive environmental impedance becomes larger as predicted by the calculation. From discussion of the shape of the Coulomb diamond, it is concluded that the observed enlargement of the Coulomb gap is due to the electromagnetic environment effect of the Coulomb blockade.
