AbstractWe report on the structural analysis of multiwall carbon nanotubes (MWNTs), produced by DC arc discharge in hydrogen gas, using a scanning tunneling microscope operated at ambient conditions. On a microscopic scale the images show tubes condensed in ropes as well as individual tubes which are separated from each other. Individual nanotubes exhibit various diameters (2.5-6 nm) and chiralities (0-30Å). For MWNTs rope, the outer portion is composed of highly oriented nanotubes with nearly uniform diameter (4-5 nm) and chirality. Strong correlation is found between the structural parameters and the electronic properties in which the MWNTs span the metallic-semiconductor regime. True atomic-resolution topographic STM images of the outer shell show hexagonal arrangements of carbon atoms that are unequally visible by STM tip. This suggests that the stacking nature of MWNTs, may effect the electronic band structure of the tube shells. Unlike other MWNTs produced by arc discharge in helium gas, the length of the tubes are rather short (80-500 nm), which make it feasible to use them as a components for molecular electronic devices.

Recent experiments have shown that thermal conductivity of carbon nanotubes can be more than twice that of diamond. It should be noted that high mechanical strength often comes with high thermal conductivities. Recent experiments have shown that the thermal conductivity of carbon nanotubes can be as high as 3000 to 6000 W/m K at room temperature, which is more than twice that of diamond. It was recently shown by Alex Zettl and his group at the University of California, Berkeley that the relative motion between different shells of multiwall carbon nanotubes has some unique properties and can serve as excellent mechanical bearings that do not undergo any wear. Recent work has led to multifunctional probes, which, besides topography, can detect thermal, electrical, magnetic, and optical signals at nanoscales. The engineering challenge now is to develop microelectromechanical systems (MEMS)-based probes that integrate multiple functions on a single tip.
