LaAlO3 Single Optical Crystal 3 Inches Good Lattice Matching

LaAlO3 single crystal


LaAlO3 single crystal is the most important industrial and large-scale high temperature superconducting thin film substrate single crystal material. LaAlO3 crystal is the substrate material for epitaxial growth of high temperature superconducting thin films and giant magnetoresistance thin films because of its good lattice matching with a variety of perovskite structure materials.

At the same time, lanthanum aluminate crystal has low dielectric constant and good microwave dielectric properties, so it is suitable for low loss microwave amplifier and dielectric resonance applications.

Corestro offers a single crystal substrate with a maximum diameter of 3 inches.
