Complex tunnel nanostructures on the base of atomic and molecular clusters were studied by scanning tunneling microscopy. It was shown that clusters can form an ordered two-dimensional lattice in the monolayer. Electron transport through one- and two-barrier tunnel nanostructures was investigated at room temperature. The decreasing of the Coulomb blockade potential of the tunnel nanostructure with increasing of cluster nuclearity was observed.
