项目摘要

This investigation has been carried out on the basis of the physics of insulating engineering and dielectric physics. The investigators used the Maxwell-displacement-current-measurement method, which has been developed by the investigators, in this investigation, and obtained the following results. (1) We have developed the method for analyzing the electrical properties of organic monolayrs on a material surface by means of the MDC technique. We succeeded in determining the dipole moment of polar molecules including phospholipids and mesogenic liquid crystals. Starting from the Brownian motion equation of polar molecules on a material surface, we analyzed the displacement of polar molecules and derived the MDC equation representing the dynamic motion of organic monolayrs with the application of external stimulation. We used this result and analyzed the transient behavior of monolayrs. (2) Using the MDC technique, we analyzed the cis-trans photoisomerization of monolayrs and also examined the displacement of charged carriers between the adjacent two monolayrs by mean of the inelastic tunneling spectroscopy. Further, using the surface potential technique, we examined the displacement of electronic charges between electrodes and organic monolayrs, and determined the spatial distribution charges and the electronic density of states in organic monolayr films such as polyimide and phtalocyanins. (3) We for the first time succeeded in the detection of the transmission of conformational change in organic mixed monolayrs as well as in the liquid crystal cells by means of the MDC technique.
这项研究是在绝缘工程物理学和介电物理学的基础上进行的。研究人员在本研究中使用了研究人员开发的麦克斯韦位移电流测量方法,并获得了以下结果。(1)本文发展了用MDC技术分析材料表面有机单层膜电学性质的方法。我们成功地确定了包括磷脂和介晶液晶在内的极性分子的偶极矩。从极性分子在材料表面的布朗运动方程出发,分析了极性分子的位移,导出了在外界刺激作用下有机分子单分子膜动力学运动的MDC方程。我们利用这个结果分析了单层膜的瞬态行为。(2)使用MDC技术,我们分析了顺-反式光致异构化的单层膜,也检查了相邻的两个单层膜之间的电荷载流子的位移的非弹性隧道光谱的装置。此外,使用表面电位技术,我们研究了电极和有机单层膜之间的电子电荷的位移,并确定了空间分布的电荷和电子态密度的有机单层膜,如聚酰亚胺和酞菁。(3)我们第一次成功地在检测的有机混合单层以及在液晶盒中的MDC技术的手段的构象变化的传输。
