CNTFET gate design with tolerance to metallic CNTs

This study focuses on the design of logic gates built with Carbon Nanotube Field Effect Transistors (CNTFETs). Due to current fabrication issues, a certain percentage of the carbon nanotubes (CNTs) are not functioning as semiconductors but as simple conductors (called metallic CNTs). Therefore, it is necessary to arrange the transistors within a gate in a way that the character of the gate is maintained, while the performance is affected as little as possible. In this study an approach is described using one nanotube for more than one transistor.
