Structure of nanodiamonds

The structure of nanodiamonds is considered within the model of icosahedral nanoparticles with a local diamond-like order and a shell structure. The diffraction from nanoparticles with noncrystallographic (in particular, icosahedral) packings of atoms is analyzed. It is demonstrated that the method proposed for calculating the intensity of coherent scattering by clusters of identical polyatomic aggregates is applicable to the entire diversity of carbon structures existing in the nanoworld.[PUBLICATION ABSTRACT]
