摘要

We report on the fabrication of bottom gate top contact organic field effect transistors with hybrid gate dielectric and TIPS-Pentacene:PS blend as active layer on PowerCoat™ HD 230 paper substrate. The hybrid dielectric layer leads the devices operated at relatively low voltage of −10 V with avg. and maximum field effect mobility of $0.52(pm 0.16)$ and 0.78 cm2 V−1 S−1 respectively, with near zero threshold voltage and on-off current ratio approaching ~104. The devices have shown excellent operational stability when tested with DC bias stress of $mathrm{V}_{mathrm{DS}}=mathrm{V}_{mathrm{GS}}=-10 mathrm{V}$ for 1 h and minuscule changes in electrical characteristics were observed with continuous multiple transfer cycle scans. In addition, we have demonstrated a resistive load inverter circuit with varying the load resistance with these paper OFETs.
