Abstract

An acoustic surface wave component for which metallic strip structures of copper are applied on a piezoelectric material wherein the metallic strip structures have a polycrystalline and/or monocrystalline structure and/or are present in an amorphous state and consist of a basic copper material to which 0 atom percent to a maximum of 10 atom percent of one or more other metallic elements, an alloy and/or a compound are mixed, and that the strip structures are coated with or surround by one or more diffusion barrier layers.
