使用飞行时间技术，可以在液晶光电导体六戊氧基苯并菲的不同温度和相区中观察到不同的传输机制、深捕获、多个浅捕获和理想的本征传输。载流子迁移率的温度和场依赖性已确定高达 1 X 10(-3) cm2/V s；该值大大超过了最常用的有机光电导体的迁移率。实验反映了液晶系统领域中新颖的各种传输现象。
Using a time-of-flight technique, different transport mechanisms, deep trapping, multiple shallow trapping, and ideal intrinsic transport, can be observed in the different temperature and phase regions of the liquid-crystalline photoconductor hexapentyloxytriphenylene. The temperature and field dependences of carrier mobilities Up to 1 X 10(-3) cm2/V s have been determined; this value exceeds considerably the mobilities of the most commonly used organic photoconductors The experiments reflect a variety of transport phenomena which are novel in the field of liquid-crystalline systems.
