We report for the first time experimental investigations on SOI, Si 1-x Ge x OI & GeOI Tunnel FET (TFET). These devices were fabricated using a Fully Depleted SOI CMOS process flow with high k-metal gate stack, enabling 2 decades lower I OFF (~30fA/µm) compared to co-processed CMOS. We successfully solve the TFET bipolar parasitic conduction by a novel TFET architecture, the Drift Tunnel FET (DTFET), with improved OFF state control. Concerning the ON current issue, we improve the SOI p (resp. n) TFET
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
