l)-DIMENSIONAL HEIGHT-HEIGHT CORRELATION FUNCTIONS FOR SELF-AFFINE FRACTAL MORPHOLOGIES
نویسنده
چکیده
We study analytic forms in Fourier space of one-dimensional heightheight correlation functions for self-affine rough surfaces. Comparisons with complex systems suggest three alternative models. However, only the model Cl(k) m (1 + a]#-(r+2H) permits analytic calculation of important surface roughness quantities (i.e. surface width) for roughness exponents in range 0 5 HI 1. Furthermore, the implications of the results to experimental roughness studies by means of STM-AFM are discussed. Copyright

Dynamical scaling behavior in two-dimensional ballistic deposition with shadowing.
The dynamical scaling behavior in two-dimensional ballistic deposition with shadowing is studied as a function of the angular distribution of incoming particles and of the underlying lattice structure. Using a dynamical scaling form for the surface box number, results for the scaling of the surface fractal dimension are also presented. Our results indicate that, in addition to the usual self-af...
متن کاملStatistical characterization of the lapping plate surface morphology evolution in a diamond charging process
The topographical evolution of a lapping plate surface during a diamond charging process was followed by analysis of atomic force microscopy (AFM) images. AFM measurements were performed in the tapping mode on several Sn–Sb alloy lapping plates containing different amounts of encrusted diamond particles on their surface. Such plates were processed under different charging times at the Lapping P...
متن کاملAnisotropic self-affine properties of experimental fracture surfaces
The scaling properties of post-mortem fracture surfaces of brittle (silica glass), ductile (aluminum alloy) and quasi-brittle (mortar and wood) materials have been investigated. These surfaces, studied far from the initiation, were shown to be self-affine. However, the Hurst exponent measured along the crack direction is found to be different from the one measured along the propagation directio...
متن کاملDense Analytic Subspaces in Fractal L 2 -spaces
We consider self-similar measures µ with support in the interval 0 ≤ x ≤ 1 which have the analytic functions e i2πnx : n = 0, 1, 2,. .. span a dense subspace in L 2 (µ). Depending on the fractal dimension of µ, we identify subsets P ⊂ N 0 = {0, 1, 2,. .. } such that the functions {en : n ∈ P } form an orthonormal basis for L 2 (µ). We also give a higher-dimensional affine construction leading t...
متن کاملSubmonolayer homoepitaxial films growth
In this work we investigate influence of substrate temperature on the surface morphology for substrate coverage below one monolayer. The model of film growth is based on random deposition enriched by limited surface diffusion. Also anisotropy in the growth is involved. We found from computer simulations for simple cubic lattice and solid-on-solid model, that surface morphology changes with incr...
