Inkjet Printing of Carbon Nanotube Complementary Inverters

Abstract

The fabrication technology for emerging printed and flexible electronics is currently suboptimal. Although inkjet technology is a powerful tool for producing single-walled carbon nanotube (SWCNT) film transistors, inkjet printing at moderate temperatures (<100 °C) of complementary logic gates that are suitable for plastic substrates has yet to be realized. In this study, we describe how we surmounted these difficulties by combining SWCNTs and room-temperature-processable polymer dopant. We have successfully inkjet-printed SWCNT complementary inverters at 90 °C, thereby improving the performance limit of SWCNT electronics.
