Pulsed laser deposition of nanostructured carbon films for field emission

摘要

The technology of target production was developed and the regimes of their irradiation was determined. The investigation was made of electrofield emission characteristics of thin nanodiamond and glassy carbon films deposited by laser ablation of diamond and glassy carbon targets. X-ray analysis and Raman spectroscopy showed that there was no phase change in the target substance during the process of the target substance deposition upon the substrate. Emission currents up to 10 mA/cm~2 in the field of 20 V/μm were obtained. The numerical simulation of temperature fields distribution in the target material was carried out.
