High-energy ion bombardment
WebBecause high energy ion bombardment is known to suppress fluorocarbon deposition, it seems likely that changes in surface chemical composition in their presence enhances the contribution of lower ... WebAbstract Dense nanoscale twins were introduced into Cu films and nanowires through bombardment with high-energy Ar + ions at low temperatures. Both the twin boundary density and indentation hardness of the ion-irradiated Cu films increased with decreases in the bombardment temperature.
