    Ion irradiation effects on conduction in single-wall carbon nanotube networks

    We have measured how irradiation by Ar+ and N+ ions modifies electronic conduction in single-wall carbon nanotube (SWNT) networks, finding dramatically different effects for different thicknesses. For very thin t...

    INFLUENCE OF CATALYST AND CARBON SOURCE ON THE SYNTHESIS OF CARBON NANOTUBES IN A SEMI-CONTINUOUS INJECTION CHEMICAL VAPOR DEPOSITION METHOD

    The injection chemical vapor deposition (CVD) method allows the semi-continuous production of pure multi-wall carbon nanotubes (MWCNTs). In order to find the most efficient catalyst material and carbon source,...
