Digital VLSI logic technology using Carbon Nanotube FETs: Frequently Asked Questions

Carbon nanotube field-effect transistors (CNFETs) show promise as extensions to silicon-CMOS. Ideal CNFET circuits can potentially provide 20X energy-delay-product benefits over silicon-CMOS at the 16 nm technology node. However, several challenges must be overcome before such performance benefits can be experimentally realized. In this paper, we present a brief overview of CNFET technology, and address commonly raised concerns through a series of frequently asked questions (FAQs). We also provide a CNFET technology outlook which includes a survey of challenges as well as existing and potential solutions to these challenges.
