Electrical properties of organic field-effect transistors based on ribbon-like tips-pentacene crystals

By the droplet-pinned crystallization method organic field-effect transistors with good device performance were fabricated based on ribbon-like TIPS-pentacene crystals. The electrical property of OFETs with ribbon-like TIPS-pentacene crystals developed by different concentration solutions is investigated. It is revealed that large and highly textured crystals tended to result in high mobility and small electrical hysteresis window.
