Journal of Convex Analysis 11 (2004), No. 1, 059--068 Copyright Heldermann Verlag 2004 A Relaxed Model for Step-Terraces on Crystalline Surfaces Matthias Kurzke Max-Planck-Institut, Inselstr. 22-26, 04103 Leipzig, Germany, kurzke@mathematik.uni-leipzig.de Marc Oliver Rieger Center for Nonlinear Analysis, Carnegie Mellon University, Pittsburgh, U.S.A., rieger@andrew.cmu.edu We study a variational problem that has been introduced to describe step-terraces on surfaces of so-called "unorthodox" crystals. Motivated by physical considerations, we use Γ-convergence to derive a simplified model that can be solved explicitly. Keywords: Surfaces of crystals, step-terraces, unorthodox crystals, variational problems, Γ-convergence. FullText-pdf (607 KB) for subscribers only. |
