Starting from water monomers adsorbed on Cu(111), we have induced the formation of small ice clusters via the tip of a low temperature scanning tunnelling microscope. We show that diffusion, formation, and structural changes of clusters are induced by electrons coupling to vibrational modes of the molecule. The manipulation transfers enough energy into the system to induce stable clusters both two-dimensional and three-dimensional ones, including the important cyclic hexamer. Only the three-dimensional clusters develop a localized gap around the Fermi energy of approximate to76 meV, which varies for different positions on a cluster. (C) 2002 American Institute of Physics.
