    Notes: Abstract Gold particles deposited on graphite in vacuum have been studied by STM observation in air. Liquid-like coalescence between small gold-particles has been observed near room temperature. Preparation of small particles in vacuum is discussed. Small particles are formed in nucleation process if the degree of coalescence of particles is reduced. Over 400 Au particles of 5 nm in diameters with a narrow size-distribution with FWHM 2 nm and a high density of 3×1012/cm2 is prepared by evaporating gold in a vacuum of about 2×10−5 Torr and at the substrate (HOPG) temperature of 20°C.

    In-situ STM observation of coalescence of metal particles in liquid (1993)
    Springer

    Notes: Abstract We have madein-situ observation of electrodeposition on the graphite surface in electrolyte(0.5 mM-Bi2O3, 10 mM-HClO4) by means of Scanning Tunneling Microscopy(STM). We have observed the growth and the stripping of Bi metal particles of about 10 nm in diameter, with increase and decrease in the electrode potential, respectively. The STM images are taken in real time in a period of about 30 sec. They show that small particles grow in the initial stage, come in contact with each other, and coalesce in the contact area connecting two neighboring particles.

    Ab-initio molecular dynamics simulation of monolayer C60 thin film on silicon (100) surface (1993)

    Notes: Abstract Two dimensional band structure is calculated for a triangular lattice of C60 molecules by using a mixed-basis approach in which wave functions are expanded with not only plane waves but also 1s and 2p atomic orbitals of carbon atoms. The present analysis modeling a charge transfer from Si dimers of the Si (100) surface suggests the existence of a small Fermi-surface. The resulting partial charge distribution is consistent with the recent STM observation of specific stripes, the direction of which is parallel to that of the topmost double bond of C60, regardless of the intermolecular interaction. It is concluded that the orientation of C60 on the Si surface is mainly determined by the direction of dimer arrays and not by the interaction between C60 molecules.

    Notes: Abstract Light emission and scattering are analyzed for the plume of vapor produced by laser excitation of the solid target of Group II, III and IV elements. Spectroscopic evidences suggest that the plume consists of microclusters of target elements. The size of microclusters is estimated to be 0.6 nm in diameter.
