SWNT ropes with SWCNT probe

AFM phase contrast image of SWCNT bundles taken with a SWCNT 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.

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

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

A high yield SWCNT growth on a silicon substrate with alumina supported iron catalyst produces bundles of tubes sourced at catalyst sites. AFM height image.
