A 2V Organic Complementary Inverter

Abstract

A complementary organic thin-film transistor technology uses pentacene and F16CuPc as the p-type and n-type materials, respectively. The semiconductors are patterned by vacuum deposition through an integrated shadow mask, while tilting the substrate. Organic complementary inverters are realized that display an almost ideal inverter curve at a supply voltage of 2V, showing a gain of 14 and a noise margin of 0.65V
