Deposition of nano-crystalline graphite films by cathodic plasma electrolysis
Atmospheric pressure plasma deposition (APPD) of nano-crystalline graphite films on titanium substrate from a predominantly ethanol liquid phase was carried out under varying applied voltage. A thorough study of the plasma electrolytic deposition mechanisms has been performed. The investigation of the composition, structural properties, and the morphology of these graphite coatings have been performed by visible and UV Raman spectroscopy, X-Ray Photoelectron Spectroscopy, Scanning Electron Microscopy and EDAX elemental analysis. The experimental evidence of the reduction of the work function and the enhancement of the plasma intensity with the presence of the carbon film has been reported. These properties make such nano-crystalline graphite coatings very attractive for the production of inexpensive cold cathodes for electronics and plasma devices.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
