We can provide high temperature superconducting thin film substrate , magnetic thin films and ferroelectric thin film substrate , semiconductor crystal , optical crystal , laser crystal materials ,at the same time provide orientation and foreign universities and research institutes to provide high quality ( ultra smooth ,ultra smooth , ultra clean)
(La,Sr)(Al,Ta)O3 is a relatively mature non-luan crystal perovskite crystal, which is well matched with high-temperature superconductors and various oxide materials. In the process of a large number of actual research and use, it is expected to replace lanthanum aluminate (LaAlO3) and strontium titanate (SrTiO3) for giant magnets and superconducting devices.
