Abstract (in Japanese) (See Japanese page) 
(in English) Organic single crystalline film devices are known to show high mobility that exceed the mobility of amorphous silicon thin films, however there has been little information on the basic study of transport mechanism in the organic single crystals. Electric field distribution which governs the carrier behavior in the organic devices can be evaluated by using the electric field induced second harmonic generation (EFISHG) measurement. In this report we have conducted time-resolved microscopic measurement, TRM-SHG, to visualize carrier transport in anisotropic TIPS pentacene single crystals. Strong temperature dependence of the SHG signal observed at the electrode edge suggests Schottky injection process. We have directly calculated the carrier mobility taking into account the potential drop, and concluded that the Marcus theory is appropriate to explain the carrier transport in the TIPS pentacene thin film. TRM-SHG method is an effective way to directly visualize transport process and evaluates injection and transport process simultaneously.
