Fig. 1From: Characteristics and Mechanism of Cu Films Fabricated at Room Temperature by Aerosol Deposition a Surface roughness of Al2O3 substrates and (b) adhesive strength of Cu films grown on Al2O3 substrates with different surface roughness values. The inset shows a schematic diagram of adhesion force measuring method. The adhesive strength is calculated from the maximum tensile force or pull-off forceBack to article page
