Strontium Lanthanum Aluminate Wafer LaSrAlO4 Crystal Substrate

Strontium lanthanum aluminate, LaSrAlO4 substrate (single crystals). LaSrAlO4 from melting temperature to a lower temperature all not have luan crystal phase transition, and have the same structure to high-temperature superconductor YBCO, have a low coefficient of thermal expansion than other perovskite structure crystals. it can be able to deposited Films at a lower temperatures, Thereby improving the lattice mismatch and reduce stress.
