Carbon nanotube FETs decorated by gold nanoparticles: Electrical properties and mechanism

Abstract

The electrical transport behavior of carbon nanotube field-effect transistors (CNT-FETs) decorated with gold nanoparticles (NPs) has been investigated. After decoration with Au NPs, the Ion/Ioff ratios of nanotube FETs decrease and some of the p-type devices even change into metallic ones. The Au NPs decrease the contact resistances between the CNTs and… (More)
