Study on the charge fluctuation in molecular conductors

在分子固体中，分子的电荷为0.5+，分子电荷呈现静态或动态偏离，如(0.5+d，0.5-d)，这种偏离有时以波动的形式存在，取决于分子在固体中的排列。在本研究项目中，我们提供了实验数据来支持对这种偏差的起源的解释。在一些材料中，我们证明了这种偏离或涨落带来了新类型的铁电。铁电材料是制造电子和光学器件不可缺少的材料，这种新型铁电材料有望应用于快速响应的光学器件。

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.
