Polymer Gate Dielectrics and Conducting-Polymer Contactsfor High-Performance Organic Thin-Film Transistors

Abstract

Organic thin-film transistors and circuits have been fabricated on glass and on flexible substrates, achieving carrier mobilities of 0.3 cm2 V–1 s–1 on glass. In particular, the authors investigate how the substitution of inorganic gate dielectrics and metals with solution-processed polymers affects the performance of the transistors. Two pentacene inverters on glass are shown in the Figure (see also cover).
