Organic electronics on paper Available to Purchase

We have fabricated organic thin-film transistors and ring oscillators on paper and on flexible polyetherether ketone film using small-molecule hydrocarbon pentacene as the semiconductor and solution-processed polyvinylphenol as the gate dielectric. Transistors on paper have a carrier mobility of $0.2 cm2/V s$ and an on/off current ratio of $106,$ similar to devices on polyetherether ketone. A signal propagation delay of $22 μs$ per stage was measured for pentacene ring oscillators on polyetherether ketone film, and a signal delay of 12 ms was obtained for ring oscillators on paper.
