Printed thin-film transistors and circuits based on sorted semiconducting single-walled carbon nanotubes

Abstract

Here, we reported a valid approach to sort largediameter semiconducting single-walled carbon nanotubes (sc- SWCNTs) from commercial SWCNTs using new organic conjugated compounds and achieved more than 10 highperformance printable sc-SWCNTs inks. Print p-type and n-type TFT arrays and CMOS inverters based on sorted sc-SWCNTs were obtained on rigid and flexible substrates. Printed TFTs exhibited low operating voltage, small hysteresis, high mobility and on/off ratios. Furthermore, printed circuits also showed good performance.
