| Research Abstract |
We systematically investigated carrier mobilities of organic semiconductor films in the lateral and vertical direction, and effects of film structure and carrier mobility anisotropy on device performances. We also proposed a novel mobility measurement method of Injected CELIV that enables us to estimate thin-film mobilities for organic materials having less thermal-equilibrium carrier concentration. We discussed the relationship among film structure, anisotropy of carrier mobility, and device performances in the vertical-type organic transistors and organic photovoltaic devices where the vertical motility plays an important role.
