Study on the charge fluctuation in molecular conductors

点击翻译按钮获取中文摘要

In the molecular solid, in which the molecule has an electric charge of 0.5+, the molecular charge shows static or dynamic deviation like (0.5+d, 0.5-d) and this deviation sometimes exists as fluctuation depending upon the arrangement of the molecules in the solid. In this research project, we provided experimental data to support the explanation of the origin of this deviation. In several materials, we showed that this deviation or fluctuation brought about new type of ferroelectricity. The ferroelectrics are indispensable materials for producing electronic and optical devices, and this new type of ferroelectricity is expected to be applicable to an optical device with fast response.
