This paper focuses on the growth mechanism of the multiwalled carbon nanotubes
exhibiting helical and zigzag growth morphologies. Our data support a kinetically controlled …

Rings of typically 0.5 μm diameter have been observed with the atomic force microscope
and the scanning electron microscope in carbon nanotube deposits produced catalytically …

We report here the experimental observation of complex branching phenomena in the
growth of carbon nanotubes produced under specific arc-discharge conditions. High …

We consider geometric constraints for the addition of carbon atoms to the rim of a growing
nanotube. The growth of a tube proceeds through the conversion of dangling bonds from …

Evidence is presented, through high-resolution electron microscopy images, for the open-
end growth of carbon nanotubes. Terminations of incomplete layers of carbon, seen on the …

We investigated the effect of temperature on the growth rate and structure of carbon
nanotubes using scanning electron microscopy, transmission electron microscopy, and …

Straight carbon nanotubes, carbon nanotube “knees,” Y-branches of carbon nanotubes and
coiled carbon nanotubes were grown on a graphite substrate held at room temperature by …

We present a growth model for single-walled carbon nanotubes (SWNTs) based on
experimental observation and energetic considerations. Carbon rings, observed …

A method for controlled synthesis of coiled carbon nanotubes CNTs is demonstrated, in
which three-dimensional columns of aligned CNTs are used as a template. The coiled CNTs …

The atomic structures of 124 single-walled carbon nanotubes, described by their diameter
and helicity or equivalently by the two chiral indices (u, v) that define the perimeter of each …
