Abstract

Using a Fe-containing diblock copolymer as the catalyst, single walled carbon nanotubes (SWNTs) have been grown on Si/SiO2 substrate by chemical vapor deposition (CVD) technique. Atomic force microscopic image of the grown samples exhibit interesting junction architectures in the form of T, Y, and X of small-diameter (∼ 2nm) SWNT bundles. Two-and Two-and Two-and three-terminal measurements on back-gate field effect transistors (FET) fabricated using the CVD grown junctions show interesting pristine metallic behavior and diode-like properties after burning multiple metallic contributing nanotubes.
