High performance electrolyte-gated carbon nanotube transistors

High performance electrolyte-gated carbon nanotube transistors Sami Rosenblatt, Yuval Yaish, Jiwoong Park, Jeff Gore, Vera Sazonova, and Paul L. McEuen Laboratory of Atomic and Solid State Physics, Cornell University, Ithaca, NY 14853 Department of Physics, University of California, Berkeley, CA 94720 Abstract We have fabricated high performance field-effect transistors made from semiconducting single-walled carbon nanotubes (SWNTs). Using chemical vapor deposition to grow the tubes, annealing to improve the contacts, and an electrolyte as a gate, we obtain very high device mobilites and transconductances. These measurements demonstrate that SWNTs are attractive for both electronic applications and for chemical and biological sensing.
