Features and Benefits

Single crystal lanthanum aluminate substrate lattices have a good lattice match with most perovskite-structured materials. It is an excellent substrate for the epitaxial growth of magnetic and ferro-electric thin films and high-temperature superconductors. Due to its dielectric properties it is also posses properties for low-loss microwave and dielectric resonance applications.
