Carbon nanotube FET technology for radio-frequency electronics: State-of-The-Art overview

Abstract

Carbon-based electronics is an emerging field. Its present progress is largely dominated by the materials science community due to the many still existing materials-related obstacles for realizing practically competitive transistors. Compared to graphene, carbon nanotubes provide better properties for building field-effect transistors, and thus, have higher chances for eventually becoming a production technology. This paper provides an overview on the state-of-The-Art of CNTFET technology from an electrical engineering and radio frequency analog applications point of view. Important material properties, resulting device structures, their fabrication, and the most relevant modeling concepts are briefly reviewed. Furthermore, recent results on device and circuit performance and the future prospects are presented in the context of practical requirements and applications.
