文摘

On the basis of high-density and uniform assembly of Au nanoparticles on carbon nanotube (CNT) surfaceand subsequently the convenient chemical vapor deposition technique, the nanowires with carbon nanotubecore and uniform silica insulating shell were controllably synthesized and then efficiently integrated intotop-gated FETs. The study provides a simpler, lower-cost, and more controllable methodology for the uniformcoating/functionalizing of CNTs with shell layer materials such as oxide gate-dielectrics. Moreover, the as-synthesized core-shell nanowires, with inherent gate-dielectric shell layer, provide a new opportunity forefficiently and conveniently fabricating of top-gated CNTFETs and other vertical surround-gated CNTFETdevices, thus making for the development of more highly integrated circuits.
