| Outline of Final Research Achievements |
In a material composed of molecular dimer, when electrons shift to either molecule of the dimer, dipole moments appear. In some organic molecular crystals, such a new dielectricity by the positional shift of electrons in molecules is suggested. In order to search for and understand the dielectricity induced by the fluctuations of positional degrees of freedom of the charge in the dimar and molecular, we systematically stdied the dielectricity in molerular compounds, (BEDT-TTF)X and (TTM-TTP)X. We have found that anomalous enhancement of dielectric constant due tothe growth of polar domain, freezing of the domain at low temperatures, and inhomogeneous elecric polarizations in relation to randomness in the crystals.
