Abstract
Ink property for high-quality printed carbon nanotube (CNT) transistor was investigated and it was found that adhesion property of the semiconducting (s-) CNT micelles was a key issue. Anionic surfactants would prevent the s-CNT micelles from being adsorbed to the surface which was functionalized by amino groups and deteriorate the device characteristics. High-quality and high-uniform CNT transistors were obtained by using anionic surfactant free s-CNT ink, and a pressure sensor sheet was successfully demonstrated. The CNT transistors were fabricated by mask-less printing and potentialities of on-demand and on-line fabrication of large-area electronics utilizing printed CNT transistors were shown.
