Abstract:

The transition from carbon nanotubes to diamond nanocrystals by vacuum evaporation is reported. The nanocrystals were characterized by transition electron microscopy (TEM) and high resolution transition electron microscopy(HRTEM). The micrographs and corresponding diffraction patterns showed that the nanocrystals with perfect crystal structure conformed to diamond clusters. The transition mechanism and process are primarily discussed.

Key words: Carbon nanotube, Nanocrystal, Diamond, Vacuum evaporation
