Low-voltage, high-mobility organic thin-film transistors with improved stability

This paper discusses organic thin-film transistors. Due to the performance degradation of pentacene based devices, this paper proposes a six-ring fused heteroarene, dinaphtho-[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT), which has a crystal structure and thin-film morphology similar to those of pentacene, but less susceptible to oxidation. This paper reports on the static and dynamic performance and on the stability of DNTT TFTs on flexible polyethylene naphthalate (PEN) substrates.
