D. Bernaerts et al., ON A PECULIAR CONTRAST EFFECT ASSOCIATED WITH CARBON NANOTUBES, Philosophical magazine. A. Physics of condensed matter. Structure, defects and mechanical properties, 76(1), 1997, pp. 267-270
Evidence relating peculiar contrast effects observed in 0002 dark fiel
d diffraction contrast images of multishell carbon nanotubes, and the
presence of singular interplanar spacings in the tubule wall is presen
ted. The singular spacings are most probably due to the presence of sc
rolls in the tube.
