Raman scattering study on organic semiconductors having gigantic dielectric constant

混合堆叠有机半导体，由一个尺寸链组成，由一个尺寸链组成，一个替代堆叠的供体和受体分子具有分子值变化的稳定性。这些材料向电磁场展示了异常的反应。一个是一个巨大的非线性反应，另一个是一个当前的转换效应。特别是，在这个十年里，更广泛的注意力被吸引到了分子电子学的可能应用。我们已经研究了这些材料的传输、红外和光学性能。拉曼和红外光谱对开关状态的微观特性进行了测量。从实验结果来看，我们已经将堆叠在一个尺寸链上的错误（在其他词语、溶液中）发挥了这些化合物的动态特性中的重要作用。离子电荷转移化合物不符合结构性阶段的过渡。在低温度阶段发现了一种开关效应，这种效应显然是在低温度阶段，邻近的分子在哪里被缩小。我们发现，这个二进制顺序是由Solitonic Charge Carrier介导的太多当前部分中断的。

Mixed stack organic semiconductors, composed of oneーdimensional chains of alternately stacked donor and acceptor molecules have an instability to molecular valence change. These materials show anomalous response to the electric field. One is a gigantic dielectric response and the other is a current switching effect. Especially, the latter has been attracted much attention in this decade due to possible application to molecular electronics. We have investigated the transport, dielectric, and optical properties of these materials. Raman and infrared spectra were measured to investigate the microscopic properties of the switch-on state.From the experimental results, we have concluded that the stacking fault on the one-dimensional chain (in other words, solitons) play important roles in the dynamical properties of these compounds. The ionic charge transfer compounds undergo a structural phase transition. The switching effect was found to occur conspicuously in the low temperature phase, where neighboring molecules are dimerized. It was found that this dimerization order is partially broken by too much current mediated by solitonic charge carriers.
