Tóm tắt

The opportunity for measurement of X-ray spectra with the help of carbon nanotubes cathode was realized. The K/spl alpha/-spectra of the carbon, which was transferred on the copper anode as a result of field emission from cathodes containing multiwall and single-wall carbon nanotubes, was obtained. The carbon materials were found to consist from graphite-like particles. The spectrum of carbon material produced at the destruction of the cathode from single-wall nanotubes showed an enhanced intensity in the short-wave region that is indicative of stronger localization of x-electrons. The reason of such localization is likely to be due to the small size of the transferred particles.
