MECHANISM OF FORMATION OF THE INTERNAL STRUCTURE IN MULTI-WALLED CARBON NANOTUBES PRODUCED BY A DC-MAGNETRON
The specific features of growth and structure of multi-walled carbon nanotubes (MWCNT) are studied in the CNx:EuyOz films produced by the method of DC-magnetron sputtering of a combined carbon-metal oxide target in nitrogen atmosphere. It has been found that the internal structure of nanotubes corresponds to the catalytic mechanism of growth with preceding inoculation of the substrate surface by metal particles. It is supposed that the emergence of the described mechanism is determined by formation of the globules of amorphous carbon at the initial stage that play the role of a catalyst of the MWCNT growth.
