Abstract: An electrical component comprises a lead-based perovskite crystal material layer between a lower electrode on the surface of a substrate and an upper electrode, characterized in that the lower electrode comprises a stabilizing first layer made of a first material and a seeding second layer made of a second material, the first and second materials having the same chemical composition but different structural parameters and/or densities. A process for fabricating a component is also provided, in which the material with a perovskite structure may be PZT with a (100) or (111) orientation.
