Strontium Lanthanum Aluminate (SrLaAlO4) <001> Crystals and Substrates
SKU: SU4101
Strontium Lanthanum Aluminate (SrLaAlO4) Crystals and Substrates
Strontium Lanthanum Aluminate (SrLaAlO4) Crystal and Substrate has similar structure to high-temperature superconductor Yttrium Barium Copper Oxide (YBCO), which makes it a good candidate for superconducting film because of the low lattice mismatch (~3.0%). It also has lower thermal expansion coefficient than other perovskite crystals, which allows the film to grow under lower temperature and produce high quality film. It is often used for growing superconducting film, microwave and high frequency application.
