Abstract

An approach to calculating the clusters in a lithium niobate crystal’s structure, in which an oxygen octahedron is taken as a structural unit rather than an elementary cell, is substantiated for the first time. It is shown there is an energetically favorable cluster size within which the structure that forms tends to be that of a congruent crystal.
