Stress and adhesion determination of a wedged iron film system by buckle morphologies
By using the mobile property of silicone oil, a wedged iron (Fe) film system, deposited on glass substrate, has been prepared by dc-magnetron sputtering technique. The wedged Fe film is quenched by the silicone oil during deposition, and therefore contains a very high compressive stress, which is relieved by formation of a large number of telephone cord buckles. Both the buckle width l and maximum buckle deflection δ increase linearly with the film thickness, but the ratio of δ to l ( δ/l ) decreases steadily. The internal stress and adhesion energy are estimated in the frame of continuum elastic theory.
