LSAT (110) 2" x0.5 mm wafer --- 1 side epi polished - LSATe50D05C1

MTI

LSAT (LaAlO3)0.3 (Sr2AlTaO6)0.7   is a newly developing crystal with a perovskite structure and is twin-free.  LSAT has excellent lattice match with high Tc superconductors and many oxide materials. LSAT has lower melting point and  can be grown by CZ technology at a lower cost, therefore, it is expected to replace LaAlO3 and SrTiO3 as a common single crystal substrate for epitaxial oxide thin films for gain magnetic ferro-electronic and superconductive devices
