Abstract
High-resolution transmission electron microscopy (HRTEM) of multi-wall carbon
nanotubes using a spherical aberration correction of the objective lens has shown a new
possibility for the observation of nanometre-sized tubular materials. Improvement of the
image resolution along a direction parallel to that of electron incidence enables one to
obtain some information on the local height of the tubes, and in lateral directions better
than 0.14 nm at 200 kV accelerating voltage, the possibility of direct determination
of the chirality of the tubes and the observation of finer atomic structures of
carbon atoms such as ‘hexagon’ ones is suggested. Spherical aberration corrected
HRTEM begins a new stage of the structural study of nano-tubular materials.
