Effects of the growth kinetics on solute diffusion in porous films
Gabriela B. Correa, Renan A. L. Almeida, Fabio D. A. Aarao Reis
For the development of porous materials with improved transport properties, a key missing ingredient is to determine the relations between growth kinetics, structure, and transport…
Random sequential adsorption of polydisperse mixtures on lattices
Rogerio Costa Hart, Fabio David Alves Aarão Reis
Random sequential adsorption of linear and square particles with excluded volume interaction is studied numerically on planar lattices considering Gaussian distributions of lateral…
Transition from compact to porous films in deposition with temperature activated diffusion
Dung di Caprio, F. D. A. Aarao Reis
We study a thin film growth model with temperature activated diffusion of adsorbed particles, allowing for the formation of overhangs and pores, but without detachment of adatoms o…
Scaling of local roughness distributions
Fabio D. A. Aarao Reis
Local roughness distributions (LRDs) are studied in the growth regimes of lattice models in the Kardar-Parisi-Zhang (KPZ) class in 1+1 and 2+1 dimensions and in a model of the Vill…
Relaxation after a change in the interface growth dynamics
T. A. de Assis, F. D. A. Aarão Reis
The global effects of sudden changes in the interface growth dynamics are studied using models of the Edwards-Wilkinson (EW) and Kardar-Parisi-Zhang (KPZ) classes during their grow…
Simulating the initial growth of a deposit from colloidal suspensions
T. J. Oliveira, F. D. A. Aarao Reis
We study the short time properties of a two-dimensional film growth model in which incident particles execute advective-diffusive motion with a vertical step followed by horizo…

R. A. L. Almeida, S. O. Ferreira, T. J. Oliveira +1
Scaling of surface fluctuations of polycrystalline CdTe/Si(100) films grown by hot wall epitaxy are studied. The growth exponent of surface roughness and the dynamic exponent of th…
Thin film deposition with time varying temperature
T. A. de Assis, F. D. A. A. Reis
We study the effects of time-dependent substrate/film temperature in the deposition of a mesoscopically thick film using a statistical model that accounts for diffusion of adatoms…
Scaling in reversible submonolayer deposition
T. J. Oliveira, F. D. A. Aarao Reis
The scaling of island and monomer density, capture zone distributions (CZDs), and island size distributions (ISDs) in reversible submonolayer growth was studied using the Clarke-Vv…
Scaling of island size and capture zone distributions in submonolayer growth
T. J. Oliveira, F. D. A. Aarao Reis
Island size and capture zone distributions (ISDs, CZDs) are studied numerically in submonolayer growth with various critical island sizes and shapes. CZDs scaled by the variance sh…
Roughness exponents and grain shapes
T. J. Oliveira, F. D. A. Aarao Reis
In surfaces with grainy features, the local roughness shows a crossover at a characteristic length , with roughness exponent changing from to a smaller $α_2…
Phase transitions and crossovers in reaction-diffusion models with catalyst deactivation
T. G. Mattos, Fabio D. A. Aarao Reis
The activity of catalytic materials is reduced during operation by several mechanisms, one of them being poisoning of catalytic sites by chemisorbed impurities or products. Here we…
Island coarsening in one-dimensional models with partially and completely reversible aggregation
Anna Chame, F. D. A. Aarao Reis
Using computer simulations and scaling ideas, we study one-dimensional models of diffusion, aggregation and detachment of particles from islands in the post-deposition regime, i. e…

Thereza Paiva, F. D. A. Aarao Reis
We study height and roughness distributions of films grown with discrete Kardar-Parisi-Zhang (KPZ) models in a small time regime which is expected to parallel the typical experimen…

Fabio D. A. Aarao Reis
In order to estimate roughness exponents of interface growth models, we propose the calculation of effective exponents from the roughness fluctuation (sigma) in the steady state. W…
Dynamic transition in deposition with a poisoning species
F. D. A. Aarão Reis
In deposition with a poisoning species, we show that the transition to a blocked or pinned phase may be viewed as an absorbing transition in the directed percolation (DP) class. We…
Static phase and dynamic scaling in a deposition model with an inactive species

We extend a previously proposed deposition model with two kinds of particles, considering the restricted solid-on-solid condition. The probability of incidence of particle C (A) is…
Universality, frustration and conformal invariance in two-dimensional random Ising magnets
F. D. A. Aarao Reis, S. L. A. de Queiroz, Raimundo R. dos Santos
We consider long, finite-width strips of Ising spins with randomly distributed couplings. Frustration is introduced by allowing both ferro- and antiferromagnetic interactions. Free…

F. D. A. Aarao Reis, S. L. A. de Queiroz, Raimundo R. dos Santos
We address the question of weak versus strong universality scenarios for the random-bond Ising model in two dimensions. A finite-size scaling theory is proposed, which explicitly i…
