Abstract
Electron diffraction patterns from regions about 0.7 nm in diameter ha ve been obtained, in conjunction with dark-field imaging, in a scannin g transmission electron microscope to study the average helicity and t he local variations of helicity of the individual carbon nanotubes wit hin the ropes of single-walled carbon nanotubes recently produced by d ouble laser irradiation. It has been found that the predominant helici ty is that predicted theoretically, namely that giving the metallic, C -5v symmetry, (10,10) tube.
