Study of Boundary Structures.

Abstract

The scalar product (SP) formulation evaluates the boundary free energy sigma using the properties of only the two homogeneous phases (without explicitly calculating the boundry profile) that meet at the boundary. The SP method is explored in detail and is now considered ready for further use. The boundary profile can be calculated using the sum method. How to formulate this method using the cluster variation method (CVM) and the natural iteration method (NIM) is presented.
