Alumina Thin Flim LaAlO3 Substrates
Lanthanum aluminate is an inorganic compound with the formula LaAlO3, often abbreviated as LAO. It is an optically transparent ceramic oxide with a distorted perovskite structure.
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.
Small dielectric constant; low dielectric loss;good lattice matching;small thermal expansion coefficient;good chemical stability;wide energy gap;large specific surface area;certain activity; good thermal stability
