Effect of thickness ratio on ferroelectric polarization and hysteresis behaviors of BaTiO3/SrTiO3 superlattices

We study the effect of thickness ratio on the ferroelectric polarization and hysteresis behaviors of BaTiO3/SrTiO3 superlattices using Landau-Ginzburg-Devonshire theory by considering the electrostatic coupling and interface intermixing. Interface intermixing gives rise to inhomogeneous internal ele...
