Round <100> LaAlO3 Wafer Optical Substrate High Pressure Experimental Phase
LaAlO3 is a high temperature superconducting single crystal substrate. It is a good substrate material for epitaxial growth of high temperature superconducting thin films and giant magnetic thin films. Its dielectric properties are suitable for low loss microwave and dielectric resonance applications.
LaAlO3 single crystal provides a good lattice match to many materials with perovskite structure. It is an excellent substrate for epitaxial growth of high Tc superconductors, magnetic and ferro-electric thin films. The dielectric properties of LaAlO3 crystal are well suitable for low loss microwave and dielectric resonance applications.
Applications:
Electronic devices, catalysis, high temperature fuel cell, ceramics, sewage treatment, substrate materials
