Top-gate organic field-effect transistors fabricated on paper with high operational stability
- Georgia Inst. of Technology, Atlanta, GA (United States)
We report on top-gate organic field-effect transistors (OFETs) fabricated on specialty paper, PowerCoat™ HD 230 from Arjowiggins Creative Papers coated with a buffer layer composed of a polyvinyl alcohol (PVA) and polyvinylpyrrolidine (PVP) blend. OFETs operate at low voltages and display average carrier mobility values of 1.7 ± 1.1 × 10–1 cm2/Vs, average threshold voltage values of –1.4 ± 0.2 V, and average on/off current ratio of 105. OFETs also display excellent operational stability demonstrated by stable 1000 scans of the transfer characteristics and by stable on-currents displaying less than 6% change during a DC bias stress test at VDS = VGS = –10 V for 1 h. Furthermore, OFETs on paper display a decrease of only 7% in their on-state current during a bending test. Here, the performance of these OFETs on paper is comparable to that displayed by top-gate OFETs with the same geometry fabricated on glass substrates.
