Abstract

The structural, magnetic, and transport properties of bundles of buckytubes (buckybundles) have been studied. High-resolution electron microscopy (HREM) images have revealed the detailed structural properties and the growth pattern of buckytubes and their derivatives. The magnetic susceptibility of a bulk sample of buckybundles is -10.75 × 10^-6 emu/g for the magnetic field parallel to the bundle axes, which is approximately 1.1 times the perpendicular value and 30 times larger than that of C₆₀. The magnetoresistance (MR) and Hall coefficient measurements on the buckybundles show a negative MR at low temperature and a positive MR at a temperature above 60 K and a nearly linear increase in conductivity with temperature. The results show that a buckybundle may best be described as a semimetal. Using a stable glow discharge, buckybundles with remarkably large diameters (up to 200 μm) have been synthesized. These bundles are evenly spaced, parallel, and occupy the entire central region of a deposited rod. HREM images revealed higher yield and improved quality buckytubes produced by this technique compared to those produced by a conventional arc discharge.
