Aerosol Jet Printing of Single-Wall Carbon Nanotube Transistors on Plastic Substrate

Aerosol Jet printing is proposed as a method for printing large area, CNT-based transistor arrays on flexible substrate. The teaming relationship combines expertise in high resolution printing along with device and materials expertise. All semiconductor, dielectric, and conductive materials comprising the TFTs will be solution processed and printed with a single machine. This will lead to a cost effective, high throughput commercial process. The primary task during phase I will be on printing high K gate dielectrics, and aligned SWCNTs to achieve high frequency TFT performance. BENEFIT: This technology will provide a low-cost solution for fabricating large area transistor circuitry on flexible substrate. The process is highly efficient and does not require any hazardous or corrosive materials. Many applications such as disposable sensors and logic circuits will be possible.
