High-Performance Inkjet-Printed Transistors

Our recent work creating high-performance inkjet-printed carbon nanotube (CNT) transistors was summarized and highlighted by the Cockrell School of Engineering. The following is an excerpt from the article:

“We think our carbon nanontube transistor is an important step toward high-performing, low-cost printed electronics, such as smart labels, TV screens, sensors and green electronics,” said Dodabalapur, a professor in the Department of Electrical and Computer Engineering.

The team’s breakthrough is the development of a carbon nanotube transistor structure for inkjet printing with small channel lengths (by the standards of printed electronics), which allow electrons to travel along the length of the tube and conduct electricity faster. The device’s geometry, with channel lengths of 150-250 nanometers, is the shortest channel length reported thus far in which the active material is deposited by inkjet printing.
