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. © 2019 IEEE.
