Patent abstract
An electrical component includes a substrate, a first electrode layer, a structured growth layer that is thinner than the first electrode layer, a piezoelectric layer, and a second electrode layer. The growth layer is on the first electrode layer, the growth layer is structured relative to the first electrode layer, and the growth layer has a smaller surface area than the first electrode layer. The growth layer may be selected to support ordered growth relative to the piezoelectric layer.
