title: Ultrathin film organic transistors: precise control of semiconductor thickness via spin-coating.
abstract: Construction of ultrathin film organic transistors is an important challenge towards deeper understanding of the charge transport mechanism and multifunctional applications. We report on precise thickness control of ultrathin films of several organic semiconductors by using a simple spin-coating approach. Ultrathin film, n-channel organic transistors with mobilities well over 1.0 cm(2) V(-1) s(-1) have been realized and their potential in high-sensitivity gas sensing and other applications is demonstrated.
