The crystallographic structure of CdSe nanoparticles attached to carbon nanotubes has been elucidated
by means of high resolution transmission electron microscopy and high angle annular dark field scanning
transmission electron microscopy tomography. CdSe rod-like nanoparticles, grown in solution together with
carbon nanotubes, undergo a morphological transformation and become attached to the carbon surface.
Electron tomography reveals that the nanoparticles are hexagonal-based with the (001) planes epitaxially
matched to the outer graphene layer.
