Complex funnel nanostructures on the base of atomic and molecular clusters
were studied by scanning funneling microscopy. If was shown that clusters c
an form an ordered two-dimensional lattice in the monolayer. Electron trans
port through one- and two-barrier funnel nanostructures was investigated at
room temperature. The decreasing of the Coulomb blockade potential of the
funnel nanostructure with increasing of cluster nuclearity was observed. (C
