抜粋

The thin films are generally under stress from the substrate. Therefore, we relaxed the stress from a substrate and created almost stress free state. We have investigated the conduction characteristic of such BaTiO3 thin films. We have found the phenomenon in which the conductivity changes rapidly when temperature was changed, and the PTCR like effect that the conductivity decreased near curie temperature. As ferroelectrics are a class of insulators that possesses spontaneous polarization, we regard these phenomena as a new conductor-insulator transition.
