【Abstract】 Using mean_field theory, the effects of the interfacial quantum fluctuation on the dielectric property of a ferroelectric superlattice is studied within the framework of the transverse Ising model. We find that the susceptibility of the superlattice will increase along with the increase of the strength of the interfacial quantum fluctuation.更多还原
