Back in 1991 Sumio Iijima ?rst saw images of multi-walled carbon nanotubes in the TEM. Two years later, he and Donald Bethune synthesized the ?rst single-walled nanotubes (SWNTs). Since then, we have seen tremendous - vances in both the methods for nanotube synthesis and in the understanding of their properties. Currently, centimeter-long SWNTs can be readily grown at selected positions on a solid substrate, and large quantities of nanotubes can be produced for industrial applications. Signi?cant progress has been made in producing nearly homogeneous samples of nanotubes of only a few...
