Paper Abstract

This paper discusses phase field modeling of tetragonal and rhombohedral ferroelectric domain structures using three dimensional grids. The work is based on the time dependent Ginsberg-Landau (TDGL) equation in which the free energy of the system is minimized subject to constraints on the boundaries of the system. Details are presented regarding the determination of energy functions and the effects of stress and electric field on these functions.
