Abstract: Dynamics theory of ferroelectric polarons, which was developed from the shielding theory of ferroelectricity, is used to explain the polarization switch of ferroelectricity. The theoretical results are well consistent with the experimental results of TGS crystal. Based on this theory, the basic physics process of electron emissions from ferroelectricity can be studied.
