Carbon Nanotube Intra-connects With Conductive Polymers

POSTER

Abstract

The electrical and optical properties of carbon nanotube (CNT) channels, electroplated with conductive polymers were measured. Individual, single-walled CNT (SWCNT) channels were grown by chemical vapor deposition (CVD) technique precisely between very sharp metal tips on a wafer. The conductive polymers, either polycarbazole (PCZ) or, polypyrrole (PPy) were then electroplated using the CNT as an electrode. Field effect transistors were fabricated and a gate-controlled, N-shaped negative differential resistance (NDR) was observed. A large photoconductance effect, which was associated with the NDR, was demonstrated, as well.
