Abstract Motivated by recent experimental studies of Hg and Pb monolayers on Cu(001) we introduce a zero temperature model of a monolayer adsorbed on a square substrate. Lennard-Jones potentials are used to describe the interaction between pairs of adlayer-adlayer and adlayer-substrate atoms. We study a special case in which the monolayer atoms form a perfect square structure and the lattice constant, position and orientation with respect to the substrate can vary to minimize the energy. We…

Analytic theory of hexagonal monolayer interacting with hexagonal substrate
Analytic theory of the infinite rigid hexagonal monolayer interacting with hexagonal substrate is developed. The interaction potential is described by a Fourier series with up to six shells of the
Comprehensive study of the potential energy surface minima of a monolayer on (111) surface
The potential energy landscape of a monolayer adsorbed on well-ordered 111 surface is analyzed for periodic cells with a variable number of adsorbate Nads and substrate Nsub particles. The
An atomic beam diffraction study of a rare gas monolayer of square symmetry : Kr on (100) NaCl
Using cold helium atomic beam diffraction and atomic beam overlayer deposition, we have measured the structure of krypton physisorbed on the (100) face of NaCl crystals at temperatures below 50 K.
Growth of metastable high-order commensurate overlayers of Pb on Cu(001)
We studied the growth and ordering of a Pb layer deposited on Cu(001) at 150 K. Contrary to the case of adsorption of Pb at room temperature, islands readily form. These islands order in a high-order
Kr and Xe on NaCl(100): pure phases and their miscibility
Abstract Using LEED spot profile analysis (SPA-LEED) and thermal programmed desorption spectroscopy (TDS), the pure Kr/NaCl(1 0 0) system and its mixture with Xe has been studied. As substrate thin
Nonequilibrium restructuring in two-dimensional Lennard-Jones system induced by a simple square start configuration.
A molecular dynamics simulation of two-dimensional Lennard-Jones system with a simple square start configuration showed interesting dependence on high pressure conditions in short time scale, corresponding to an abrupt restructurization.


The Nonregistered-Registered Phase Transition of Rare Gas Monolayers Adsorbed on Graphite. II
As a continuation of the previous paper with the same title [J. Phys. Soc. Jpn. 46 (1979) 1852], a study is made again on the structure of rare gas monolayers physisorbed on graphite on the basis of
Structural characterization of ultra-thin metal overlayers on Cu(001) by atom beam scattering
Abstract Helium beam scattering has been used to study the growth and structures of ultra-thin metal films of Hg and Pb on Cu(001). In this article we principally describe adsorption of lead on a
Growth and structural characterization of a lead overlayer on Cu(100)
Ordered phases of Pb on Cu(100) have been studied using helium beam scattering and performing charge density calculations. At low adsorption temperature, we obtain a (5×5)R tan−1(3/4) phase. A
Static properties of physisorbed monolayers in their solid phases
Abstract Theories of two-dimensional solids on crystalline substrates are reviewed and compared with experimental data on rare gas monolayers on graphite. Current theories are shown to give a good
Multisite lateral interactions and their consequences
In a two-dimensional lattice-gas framework, the size and the effect of multisite (lateral) interactions between chemisorbed atoms (and between surface atoms in reconstruction systems) are assessed.
Three-dimensional structure of the ordered phases of Hg on Cu(001).
It is found that three of the four observed ordered submonolayer phases are high-order commensurate phases and it is shown that second-layer structural and electronic properties are influenced by those of the first layer.

Abstract It is shown that the potential energy of a gas atom interacting with a solid having a surface made up of single type of exposed lattice plane can be expressed as a Fourier series in the

Structure and dynamics of surfaces. I
Structural and dynamical properties of surfaces are of considerable importance for the elucidation of surface phenomena. For example, the adsorption of particles and chemical reactions at surfaces
Phase Transitions in Surface Films
Various two-dimensional phases are stable when adsorbed on crystalline surfaces. It is shown how the reduced dimensionality and the surface symmetry can produce some original properties in
