TEM images of (a) as-produced and (b) purified SWNTs. (c) The SEM image shows SWNT-ropes protruding from the purified nanotube soot.
Schematic diagrams of (a) experimental setup and (b) tube-Hg contact. Here is the nanotube segment submerged into Hg.
Data obtained from the purified sample. (a) Conductance plot normalized by and (b) the resistance plot of the first plateau as a function of piezopositioner displacement , measured as the tube is pushed into Hg. The straight line in (b) is the fit given by . Here is one fitting parameter and is the other fitting parameter representing the resistance per unit length of the tube. In this example and .
Histogram of electronic mean free path for (a) purified SWNTs, (b) as-produced SWNTs, and (c) commercially available purified SWNTs (HiPco-SWNT) supplied by Carbon Nanotechnologies, Inc.
