Surface diffusion on a stepped surface

Physical Review B, 1993
Surface diffusion of an adatom on a vicinal surface is investigated, using site-dependent hopping rates based on a model surface-potential profile of a regularly stepped surface. We solved analytically the coupled rate equations for the occupation probability of an adatom at a sufficiently long time, in analogy to the tight-binding theory of electronic

Growth with Surface Diffusion

Europhysics Letters (EPL), 1990
A simple growth model is investigated where particles are deposited onto a substrate randomly and subsequently relax into a position nearby where the binding is strongest. In space dimension d = 2 the surface roughness exponent and the dynamical exponent are ξ = 1.4 ± 0.1 and z = 3.8 ± 0.5.

Anisotropic diffusion of surfaces and functions on surfaces

ACM Transactions on Graphics, 2003
We present a unified anisotropic geometric diffusion PDE model for smoothing (fairing) out noise both in triangulated two-manifold surface meshes inIR3and functions defined on these surface meshes, while enhancing curve features on both by careful choice of an anisotropic diffusion tensor.

Diffusion on surfaces

Surface Science, 1975
Abstract A commentary is presented on current progress towards understanding diffusion on surfaces. Recent work by field ion microscopy shows that interactions between diffusing adatoms lead to correlated motions and add unexpected complexity to the elementary diffusion mechanisms.

Gas diffusion on graphene surfaces

Physical Chemistry Chemical Physics, 2017
Gas diffusion on graphene surfaces is a two-dimensional gas behavior, controlled not by the hopping mechanism but by molecular collisions.
