Macroscopic view of crystal-step transparency.
نویسندگان
چکیده
We study macroscopic aspects of crystal surface relaxation in 2+1 dimensions by accounting for near-equilibrium kinetics of transparent steps at the nanoscale. For slowly varying step geometries, we show that step permeability can simply renormalize a parameter in a known relation between the large-scale surface flux and the step chemical potential. This leads to a nonlinear fourth-order partial differential equation for the surface height profile.

A “v2-f Based” Macroscopic K-Ε Model for Turbulent Flow through Porous Media
In this paper a new macroscopic k-ε model is developed and validated for turbulent flow through porous media for a wide range of porosities. The morphology of porous media is simulated by a periodic array of square cylinders. In the first step, calculations based on microscopic v2 − f model are conducted using a Galerkin/Least-Squares finite element formulation, employing equalorder bilinear ve...
متن کاملPhoto-Catalytic Nanometer Composite-Crystal TiO2 Powder Synthesized by Two-Step Method
TiCl4, ammonia, inorganic salts as raw material, nanometer composite-crystal TiO2 powders were synthesized by two-step chemical method. Precursors were crystallized with different phase and stable composite-crystal TiO2 with anatase and rutile phase was prepared at low temperature. Quantitative control of crystal phase was realized. Remarkable factors includ...
متن کاملInstability of vicinal crystal surfaces with transparent steps: Transient kinetics and non-local electromigration
The steps at the crystal surfaces could be partially transparent in the sense that the migrating adatoms can cross the steps without visiting a kink position. In the case of significant transparency the velocity of a given step in a given moment is affected by atomic processes which took place at rather distant terraces in rather earlier moments. The reason is that an adatom needs time to cross...
متن کاملA Crystal Plasticity View of Powder Compaction
The cold compaction of an aggregate of powder is treated from the viewpoint of crystal plasticity theory. The contacts between particles are treated as compaction planes which yield under both normal and shear straining. The hardening of each plane represents both geometric and material hardening at the contacts between particles; the macroscopic tangent stiffness can be written in terms of the...
متن کاملCrystallization Kinetics and Characterization of Nanostructure Mica Glass-Ceramics with Optical Transparency
Transparent glasses in a system of Li2O-MgO-SiO2-Al2O3-Fchemical constituents were prepared by melt quenching method. In the fabrication of nanocrystal glass-ceramics, controlled nucleation and subsequent crystal growth were necessary to avoid loss of transparency. It was therefore important to understand thermal properties and crystallization kinetic...
