Square <100> LaAlO3 Optical Substrates Lanthanum Aluminate Laalo3 Target
LaAlO3 is a high temperature superconducting single crystal substrate. It is a good substrate material for epitaxial growth of high temperature superconducting thin films and giant magnetic thin films. Its dielectric properties are suitable for low loss microwave and dielectric resonance applications.
Applications:
High Temperature superconductors , magnetic and ferro-electric thin films
Low loss microwave applications
Dielectric resonance applications
Features:
Good lattice match to most materials with Perovskite structure
Low dielectric constant
Low microwave loss
