Hot electrons in a tunnel structure based on metal nanoclusters
  We study the effect of temperature on the tunnel current in a structure based on gold clusters taking into consideration their discrete electronic spectra. We suggest that an overheating of electron subsystem leads to the disappearance of a current gap and gradual smoothing of current--voltage curves that is observed experimentally.
