Single Wall Carbon Nanotube Printed Integrated Circuits

We aim to prepare a Phase I feasibility study of printed integrated circuits based on transistors using single wall carbon nanotube (SWCNT) fabrics. We propose to explore the feasibility of fabricating CNT circuits using ink-jet printing technology. A detailed literature and trade analysis review of CNT based ink-jet printing technology will be undertaken to provide solutions to (a) CNT separation methods (semiconducting / metallic), (b) CNT doping methods (n-type) and dielectric materials, (c) Ink-engineering, jetting and deposition, (d) Device and circuit processes, geometries, models and performance expectations and (e) Systems concerns such as nozzle actuation, variability, printing algorithms and scalability. The key strength of this proposal is our holistic approach in developing a roadmap and plan driven by clearly identified “figure-of-merits”. To assist in this down-selection process, will be guided by modeling and simulation of carbon nanotube based device/circuits. This will additionally allow for (a) process development guidance (b) accurate development of device/circuit specifications (c) allow for scenario analysis to predict tolerances, yield, power consumption and numerous performance metrics. Our approach is to make use of “off-the-shelf” printer and cartridge/nozzle technology to provide a “cost-effective” solution and facilitate rapid commercialization.
