Abstract: The peculiarities of formation of energetically equilibrium dipole oxygen-octahedral clusters in the structure of a ferroelectric crystal of lithium niobate (LiNbO3) have been studied by computer simulation. It is shown that there is an optimal relationship between the cluster energy, its size, and the Li / Nb ratio.
Keywords: lithium niobate, modeling, clusters, vacancy models, defects of sublattice.
