Phase-field model for reconstructed stepped surface.
We formulate a phase-field, or diffuse-interface, model for the evolution of stepped surfaces under surface diffusion in the presence of distinct material parameters across nanoscale terraces. In the sharp-interface limit, our model reduces to a Burton-Cabrera-Frank (BCF)-type theory for the motion of noninteracting steps separating inhomogeneous terraces. This setting aims to capture features ...
متن کاملPhase field model for composite stepped surface
We present a phase field model for the evolution of stepped surfaces with distinct material parameters across nanoscale terraces in surface diffusion. The model aims to capture the Burton-CabreraFrank (BCF)-type theory for the motion of decorated non-interacting steps separating composite terraces. Our work forms an extension of the phase field model by Hu et al. [Physica D 241, 77 (2012)]. The...
متن کاملSingle-phase-field model of stepped surfaces.
We formulate a phase-field description of step dynamics on vicinal surfaces that makes use of a single dynamical field, at variance with previous analogous works in which two coupled fields are employed, namely, a phase-field proper plus the physical adatom concentration. Within an asymptotic sharp interface limit, our formulation is shown to retrieve the standard Burton-Cabrera-Frank model in ...
متن کاملA Surface Phase Field Model for Two-Phase Biological Membranes
Abstract. We study vesicles formed by lipid bilayers that are governed by an elastic bending energy and on which the lipids laterally separate forming two different phases. The energy laden phase interfaces may be modeled as curves on the hyper-surface representing the membrane (sharp interface model). The phase field methodology is another powerful tool to model such phase separation phenomena...
متن کاملA phase-field model for cohesive fracture
In this paper a phase-field model for cohesive fracture is developed. After casting the cohesive zone approach in an energetic framework, which is suitable for incorporation in phase-field approaches, the phase-field approach to brittle fracture is recapitulated. The approximation to the Dirac function is discussed with particular emphasis on the Dirichlet boundary conditions that arise in the ...
