Lanthanum Strontium Aluminum Tantalum Oxide (La,Sr)(Al,Ta)O3 (LAST) is a kind of mature perovskite crystal with twin-free, can be grown by the Czochralski method. It is well-matched with high-temperature superconductors and other oxide materials. It is expected to replace lanthanum aluminate (LaAlO3) and strontium titanate (SrTiO3) substrate, which is used for epitaxial oxide thin films for magnetic ferro-electronic and superconductive devices.
