TEM and AFM images of a Single Walled Cabon Nanotube (SWNT) and of Multi Walled
Carbon Nanotubes (MWNTs): by Elton Graugnard, Brian Walsh, & Pedro J. de Pablo.
Carbon nanotubes were discovered as early as
1975 (probably earlier), and TEM images of them were
published by
Endo et al.. In the wake of the Bucky-Ball
(C60) fever, carbon nanotubes were "re-discovered" by Iijima
(Nature 391, 1991). They represent real 1D systems for laboratory
study. There has been much speculation about the physical and
electronic properties of carbon nanotubes. As a natural extension of
our expertise in nanoscale technology, we are using the techniques of
field emission, STM, and transport measurements to study the
electronic properties of carbon nanotubes. We have also developed a
novel technique for making good electrical contacts to the ends
of nanotubes.
