 SWNT
ropes with SWNT probe
AFM phase contrast image of SWNT bundles taken with a SWNT probe.
Phase contrast imaging resolves attractive and repulsive forces
between the nanotube probe and the nanotubes under test. Individual
nanotubes in the bundle are barely visible as the AFM resolution
is at the nanotube diameter.

 Individual
SWNT
AFM image of an individual SWNT grown on a silicon substrate with
a low yield methane process from a high purity iron nanoparticle
catalyst.

High yield SWNT
High yield SWNT on alumina supported iron catalyst. Control over
nanotube synthesis yields either individual nanotubes or several
nanotubes on surfaces.

High yield SWNT growth
A high yield SWNT growth on a silicon substrate with alumina supported
iron catalyst produces bundles of tubes sourced at catalyst sites.
