Nonlocality in Kinetic Roughening
“Suppose that we take a bin and gently and uniformly pour in granular material. As the material in the bin builds up we can identify a surface and ask the question, ‘What is the magnitude of the fluctuation in the height of surface (measured from the base of the bin)?’ Also of interest is the length scale of the surface fluctuations and how they behave dynamically as more material is added” [1]...
متن کاملInterface dynamics and kinetic roughening in fractals.
We consider the dynamics and kinetic roughening of single-valued interfaces in two-dimensional fractal media. Assuming that the local height difference distribution function of the fronts obeys Levý statistics with a well-defined power-law decay exponent, we derive analytic expressions for the local scaling exponents. We also show that the kinetic roughening of the interfaces displays anomalous...
متن کاملKinetic roughening in slow combustion of paper.
Results of experiments on the dynamics and kinetic roughening of one-dimensional slow-combustion fronts in three grades of paper are reported. Extensive averaging of the data allows a detailed analysis of the spatial and temporal development of the interface fluctuations. The asymptotic scaling properties, on long length and time scales, are well described by the Kardar-Parisi-Zhang (KPZ) equat...
متن کاملKinetic roughening in deposition with suppressed screening.
Models of irreversible surface deposition of k-mers on a linear lattice, with screening suppressed by disallowing overhangs blocking large gaps, are studied by extensive Monte Carlo simulations of the temporal and size dependence of the growing interface width. Despite earlier finding that for such models the deposit density tends to increase away from the substrate, our numerical results place...
متن کاملKinetic roughening of vicinal Si ( 001 )
The kinetic roughening behavior of vicinal Si(OO1) surfaces is studied with scanning tunneling microscopy. By analyzing the height-height correlation function of the Si layers that have been grown we found, in the case of islands growth, an algebraic roughening behavior with a roughness exponent of 0.68 * 0.05. In the step flow mode, however, we found non-algebraic roughening behavior.
