Abstract

A new type of roughness silver thin films deposited on fractal surfaces of (alpha) -Al₂O₃ ceramics were prepared by rf- magnetron sputtering. The electrical properties of the Ag films are strongly dependant on the air pressure around the sample. When air pressure decreases to a certain value, a big jump of electrical resistant happens and the Ag thin film exhibits nonlinear I-V behavior. When releasing air into the vacuum chamber and the air pressure is raised, the film resistance restores to the primitive value and the nonlinear behavior then disappears.
