The characterization of structures and device properties was studied on organic semiconducting thin films for the purpose of controlling the crystal growth and of elucidating the relationship between crystal defects and transport properties in organic thin-film transistors. Two-dimensional grazing incidence X-ray diffraction (2D-GIXD) was successfully obtained for the vapor deposited pentacene thin-films and the solution-grown TIPS-pentane films. As to the thin film growth of pentacene, thickness-dependent structural change was clearly observed in a real-time observation, and the structural change is significantly affected by exposing to air. On the other hand, large single crystals of TIPS-pentane were grown from solution phase under high magnetic filed. The 2D-GIXD patterns of solution-grown TIPS-pentane were prudently analyzed, and hole mobility in a thin film transistor based was measured and discussed.

研究有机半导体薄膜的结构和器件性能表征，以控制晶体生长并阐明有机薄膜晶体管中晶体缺陷和传输性能之间的关系。成功获得了气相沉积并五苯薄膜和溶液生长的 TIPS-戊烷薄膜的二维掠入射 X 射线衍射 (2D-GIXD)。对于并五苯的薄膜生长，在实时观察中清楚地观察到依赖于厚度的结构变化，并且结构变化受到暴露于空气的显着影响。另一方面，TIPS-戊烷的大单晶在高磁场下从溶液相中生长出来。仔细分析了溶液生长的 TIPS-戊烷的 2D-GIXD 图案，并测量和讨论了基于薄膜晶体管的空穴迁移率。
