Description of Lithium Aluminate Crystal Substrates

LaAlO2 Single Crystal is currently the most important industrialized, large-scale high-temperature superconducting thin film substrate single crystal material. Single crystals and substrates with a diameter of 2 inches or more can be obtained by a pull-up method. It matches very well with high temperatures superconducting materials such as YBaCuO and lattice and has the characteristics of low dielectric constant and low microwave loss. Therefore, it is suitable for high-temperature superconducting microwave electronic equipment (such as high-temperature superconducting microwave filters in telecommunications).
