Elucidation of mechanism of memory effect in photoswitching and development of new device

有机导体是具有高导电性的有机晶体，在激光和脉冲电场的作用下，其导电性会切换到高导电性状态。由于记忆效应的存在，高导电状态在光照射停止后仍能持续存在，并通过多种条件下的实验研究了其机理。此外，将光激发引起的性能变化的时间分辨测量技术应用于有机超导体，观察了其光响应的特征行为。

Organic conductors, which are organic crystals having high electrical conductivity, show conductivity switching to highly conductive state in the presence of laser light and pulsed electric fields. The highly conductive state can persist after the cease of photoirradiation because of memory effect, of which the mechanism is studied through the experiments in a variety of conditions. Moreover, time-resolved measurement technique of property change induced by photoexcitation is applied to organic superconductor, and characteristic behaviors in photoresponse are observed.
