There is no phase transition for LaSrAlO4 crystals from melting temperature to a lower temperature, and it has the same structure with high-temperature superconductor YBCO, but LaSrAlO4 has a lower coefficient of thermal expansion than the other perovskite structure crystals. it can be used to grow films at a lower temperature, and thereby improve the lattice mismatch and reduce stress. 

Hangzhou Shalom EO provides not only the stocked standard epi-ready MgO wafers, but also the custom type wafers upon request.
