Theoretical study of the diffusion of alkali metals on a Cu(111) surface
(Elsevier, 1997)
We present a theoretical study of the diffusion of Li, Na and K on a Cu(111) surface. Various diffusional paths are identified and characterized in terms of kinetic parameters such as diffusion constants and activation ...
Compositional modulation and surface stability in InGaP films: Understanding and controlling surface properties
(2007-04-08)
We investigate the formation of compositional modulation and atomic ordering in InGaP films. Such bulk properties - as well as surface morphologies - present a strong dependence on growth parameters, mainly the V/III ratio. ...

Nano-modification of Si-wafer surfaces using low-cost ambient air diffuse plasma
(2015-01-01)
In this paper, we demonstrated the cleaning and nano-oxidation of Si-wafer surfaces by atmospheric pressure plasma, generated in ambient air using diffuse coplanar surface barrier discharge. Plasma treatment for one second ...
Surface diffusion of k-mers in one-dimensional systems
(Elsevier Science, 2007-01-15)
The surface diffusion of interacting k-mers is studied both through analytical and Monte Carlo simulation methods in one-dimensional systems. Adsorption isotherms, jump diffusion coefficients and collective diffusion ...

DFT study of adsorption and diffusion of atomic hydrogen on metal surfaces
(Elsevier Science, 2017-10)
An extensive study of adsorption and diffusion of hydrogen atoms on (100) surfaces of fcc Au, Cu, Ag and Pt was performed by means of DFT calculations. Bulk properties of those metals were calculated and compared with ...
Surface diffusion of graphs: Variational formulation, error analysis, and simulation
(Society for Industrial and Applied Mathematics, 2004-12)
Surface diffusion is a (fourth-order highly nonlinear) geometric driven motion of a surface with normal velocity proportional to the surface Laplacian of mean curvature. We present a novel variational formulation for graphs ...
Atomic jumps during surface diffusion
(American Physical Society, 2009-12)
The characteristics of atomic displacements during surface diffusion of Cu on Cu(111) are studied by means of molecular dynamics simulations. It is found that even at very low substrate temperatures, the majority of the ...
Diffusion of interacting particles in one-dimensional heterogeneous systems
(Elsevier Science, 2006-05-01)
The equilibrium and transport properties of interacting ad-particles on bivariate heterogeneous chains are studied by combining analytical and simulation approaches. Heterogeneity is introduced in the way of patches of ...
