Self-Organized Organic Thin-Film Transistors on Plastic


  • This work was supported by a grant (M1-02-KR-01-0001-02-K18-01-007-2-0) from Information Display R&D Center, one of the 21st Century Frontier R&D Programs funded by the Ministry of Science and Technology of the Korean government.


The development of the self-organized growth of pentacence thin films on the channel region of a thin-film transistor (TFT) using surface modifications induced by organic vapor phase deposition is reported (see Figure). A bottom-contact TFT on plastic using an organic gate insulator of cross-linked poly-(4-vinylphenol) exhibited a field-effect mobility of 1.2 cm2/Vs and an on/off current ratio of ∼ 107.
