| Abstract: | The effect of broadening the levels of the nanodisc electrode on the character of the current-volt-age characteristic of the
three-electrode structure is investigated. The evaluation of broadening the electron levels in disc-like gold clusters is
based on the tunnel effect of localized electrons in the presence of the bias voltage and in the presence of the Coulomb blockade.
At low temperatures, the broadening effect leads to a strong smoothing of the current-voltage characteristic even in the structures
based on clusters that consist of tens of atoms, which is observed experimentally. |
