X-ray spectroscopic study of carbon produced at destruction of field cathodes from carbon nanotubes
Proceedings. 3rd Annual Siberian Russian Workshop on Electron Devices and Materials - Tập 1 - Trang 2 pp. - 2002
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.
