Single-walled carbon nanotubeCNT Carbon Nanotube CAS Number : 308068-56-6
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. The article, "Hysteresis free carbon nanotube thin film transistors comprising hydrophobic dielectrics" in the Journal of Applied Physics Letters discloses how this new materials package addresses these performance issues
