High-temperature superconducting thin film LaAlO3 single crystal substrate
High-temperature superconducting thin film LaAlO3 single crystal substrate
LaAlO3 single crystal is the most important industrialized, large-size high-temperature superconducting thin film substrate single crystal material. Its growth with the Czochralski method , 2 inches in diameter and larger single crystal and the substrate can be obtained. It's suitable for the production of high temperature superconducting microwave electronic devices (such as long-distance communication in high-temperature superconducting microwave filters etc.)
