XRCC and NanoIntegris advance flexible electronic devices with thin film transistor package


A new materials package developed by Xerox Research Centre of Canada (XRCC) and NanoIntegris, a subsidiary of Raymor Industries, will help advance the rapidly expanding wearable and flexible electronics market.

The thin film transistor package combines a novel dielectric ink developed at the XRCC, with a high purity, single-walled carbon nanotube ink developed by NanoIntegris. The materials package improves the overall performance of printed high-mobility p-type transistors.

Printing transistors, the next frontier in wearable and flexible electronics, offers manufacturers a low-cost way to add intelligence or computing power to a wide range of surfaces, such as plastic or fabric. Printable semiconducting and dielectric materials enable flexible tags, sensors and displays. Compatibility between semiconducting and dielectric materials is critical for reliable processing and device performance.

One of the challenges that has limited the implementation of single-walled, carbon nanotube-based thin film transistors is that they exhibit considerable hysteresis. The thin film transistor package overcomes this issue by using Xerox ink as a dielectric and encapsulant, ensuring compatibility between semiconducting and dielectric materials, and enabling reliable processing and device performance. An upcoming article in the Journal of Applied Physics Letters discloses how this new materials package addresses these performance issues.

“XRCC and NanoIntegris are providing a materials package that enables fabrication of highly functional printed electronic components,” said Brynn Dooley, manager of XRCC’s Electronic Materials Business. “This new materials solution will help our clients with their innovation mandates.”
