Strontium Lanthanum Aluminate (SrLaAlO4) Crystal Substrate

Strontium Lanthanum Aluminate Crystal Substrate
Product Strontium Lanthanum Aluminate (SrLaAlO4) Crystal Substrate
Part Number SB16
Density 5.92 g/cm3
Synonyms Single Crystal SrLaAlO4 Substrate, SrLaAlO4 Substrate

Strontium Lanthanum Aluminate Crystal (SrLaAlO4) has no twinning and phase transition from the melting point temperature to the low temperature. It has the same structure as the high-temperature superconductor YBCO. The < 001 > surface has a moderate lattice mismatch (2.5-3.5%) compared with other substrates. At the same time, the thermal expansion coefficient of the crystal is lower than that of other perovskite crystals, and the film can be deposited at a lower temperature to improve the lattice mismatch and reduce it Stress.
