Synthesis and Characterization of Single-Wall Carbon Nanotubes Grown by Chemical Deposition of Ethanol Vapor
In this work the method of single-wall carbon nanotube synthesis based on chemical vapor deposition from ethanol vapor has been developed. The films grown have been characterized in detail by the electron microscopy and the Raman scattering techniques. A typical split tangential mode (at 1592 cm-1) and a number of "breathing" modes (150-270 cm-1) have been revealed in the Raman spectra for a variety of synthesis regimes. It was possible to change the geometrical parameters of nanotubes by playing with the synthesis conditions. A key role of the catalyst (Co, Co:Mo) preparation has been revealed. A special procedure of the catalyst crystal growth has been developed.
