Lattice-gas modeling of CO adlayers on Pd(100)
Da-Jiang Liu
Using a lattice-gas model with pairwise interactions, we study the ordered structures, coverage dependence of the heat of adsorption, and other experimentally observable behavior o…
Crossover between mean-field and Ising critical behavior in a lattice-gas reaction-diffusion model
Da-Jiang Liu, N. Pavlenko, J. W. Evans
Lattice-gas models for CO oxidation can exhibit a discontinuous nonequilibrium transition between reactive and inactive states, which disappears above a critical CO-desorption rate…
Catalytic CO Oxidation on Nanoscale Pt Facets: Effect of Inter-Facet CO Diffusion on Bifurcation and Fluctuation Behavior
N. Pavlenko, J. W. Evans, Da-Jiang Liu +1
We present lattice-gas modeling of the steady-state behavior in CO oxidation on the facets of nanoscale metal clusters, with coupling via inter-facet CO diffusion. The model incorp…
Current-Induced Step Bending Instability on Vicinal Surfaces
Da-Jiang Liu, John D. Weeks, Daniel Kandel
We model an apparent instability seen in recent experiments on current induced step bunching on Si(111) surfaces using a generalized 2D BCF model, where adatoms have a diffusion bi…
A quantitative theory of current-induced step bunching on Si(111)
Da-Jiang Liu, John D. Weeks
We use a one-dimensional step model to study quantitatively the growth of step bunches on Si(111) surfaces induced by a direct heating current. Parameters in the model are fixed fr…
