Flexible nano-hybrid inverter based on inkjet-printed organic and 2D multilayer MoS2 thin film transistor

Abstract

We report a novel platform on which we design a flexible high-performance complementary metal–oxide–semiconductor (CMOS) inverter based on an inkjet-printed polymer PMOS and a two-dimensional (2D) multilayer molybdenum disulfide (MoS2) NMOS on a flexible substrate. The initial implementation of a hybrid complementary inverter, comprised of 2D MoS2 NMOS and polymer PMOS on a flexible substrate, demonstrates a compelling new pathway to practical logic gates for digital circuits, achieving extremely low power consumption with low sub-1nA leakage currents, high performance with a voltage gain of 35 at 12V supply voltage, and high noise margin (larger than 3V at 12V supply voltage) with low processing costs. These results suggest that inkjet-printed organic thin film transistors and 2D multilayer semiconducting transistors may form the basis for potential future high performance and large area flexible integrated circuitry applications.
