Universal Coarsening and Giant-Cluster Formation in Growing Interfaces
Renan A. L. Almeida, Tiago J. Oliveira, Jeferson J. Arenzon +1
Clusters formed by fluctuations of two-dimensional (2D) directed interfaces around a threshold level have been extensively studied at equilibrium and in nonequilibrium steady state…
Critical clusters in liquid crystals: Fractal geometry and conformal invariance
Renan A. L. Almeida, Jeferson J. Arenzon
We study the two-dimensional domain morphology of twisted nematic liquid crystals during their phase-ordering kinetics [R. A. L. Almeida, Phys. Rev. Lett. 131 (2023) 268101], which…
Critical percolation in the ordering kinetics of twisted nematic phases
Renan A. L. Almeida
I report on the experimental confirmation that critical percolation statistics underlie the ordering kinetics of twisted nematic phases in the Allen-Cahn universality class. Soon a…
Energy-lowering and constant-energy spin flips: Emergence of the percolating cluster in the kinetic Ising model
Amanda de Azevedo-Lopes, Renan A. L. Almeida, Paulo Murilo C. de Oliveira +1
After a sudden quench from the disordered high-temperature phase to a final temperature below the critical point , the non-conserved order parameter dyn…
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…
Phase-ordering kinetics in the Allen-Cahn (Model A) class: universal aspects elucidated by electrically-induced transition in liquid crystals
Renan A. L. Almeida, Kazumasa A. Takeuchi
The two-dimensional (2d) Ising model is the statistical physics textbook example for phase transitions and their kinetics. Quenched through the Curie point with Glauber rates, the…
Roughness and Correlations in the Transition from Island to Film Growth: Simulations and Application to CdTe Deposition
Tung B. T. To, Renan A. L. Almeida, Sukarno O. Ferreira +1
Using kinetic Monte Carlo simulations, we develop a framework to relate morphological properties and microscopic dynamics during island growth, coalescence, and initial formation o…
Initial pseudo-steady state & asymptotic KPZ universality in semiconductor on polymer deposition
R. A. L. Almeida, S. O. Ferreira, I. Ferraz +1
The Kardar-Parisi-Zhang (KPZ) class is a paradigmatic example of universality in nonequilibrium phenomena, but clear experimental evidences of asymptotic 2D-KPZ statistics are stil…
Kardar-Parisi-Zhang Universality, Anomalous Scaling and Crossover Effects in the Growth of Cdte Thin Films
Renan A. L. Almeida
We report on the growth dynamic of CdTe thin films for deposition temperatures () in the range of to . A relation between moun…
Temperature effect on (2+1) experimental Kardar-Parisi-Zhang growth
R. A. L. Almeida, S. O. Ferreira, I. R. B. Ribeiro +1
We report on the effect of substrate temperature (T) on both local structure and long-wavelength fluctuations of polycrystalline CdTe thin films deposited on Si(001). A strong T-de…
Universal fluctuations in the growth of semiconductor thin films
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…
