Once University films were deposited, atomic force microscopy investigations were achieved in order exam emphasize University impact of University substrate temperature on University topographical, mechanical and tribological features. The effects mentioned an important have an effect on of University substrate temperature on topographical, mechanical and tribological properties of University investigated chromium nitride thin films. The microelectronic industry has been growing swiftly over University past 10 20 years, as has its reliance on thin film deposition ideas for components manufacturing.
