| Research Abstract |
It is necessary to enhance polarization to obtain new materials with giant dielectric constants. Polarization is given by the product of charge and its displacement. We tried to enhance the polarization using migration of electrons in the artificial structures. Two kind of artificial structures, artificial superlattices with two conductive atomic layers and imhomogenous structure formed by spinodal decomposition, were formed, and found that the electron migration in these artificial structures enhance the polarization, giving rise to an marked increase of dielectric constants. The similar enhancement was observed when the ionic migration in a solid electrolyte was use to generate polarization.
