Abstract:We report fabrication and experimental characterization of metallic single-walled carbon nanotube (SWNT) mixers. Metallic nanotubes attached to gate dielectric (SiO2) and suspended nanotubes were fabricated over Poly-Si gate structures. Devices were characterized for their RF mixing performance up to 80MHz. Under identical input signals, the suspended nanotube mixers had about 8 to 13dB higher convergence gain than the devices attached to the gate dielectric.The advantages of using patterned Poly-Si gate for R… Show more
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.
