Abstract

We have derived within the framework of a solid-on-solid model with anisotropic nearest-neighbor interactions an exact expression for the free energy of an arbitrarily oriented step edge or boundary on a rectangular two-dimensional lattice. The full angular dependence of the step free energy allows the determination of the surface free energy of any vicinal surface as well as the temperature evolution of the equilibrium island shape. Our method can also be applied to derive an expression for the boundary tension of an arbitrarily oriented domain boundary of the anisotropic nearest neighbor two-dimensional Ising model
