Product Description
Alumina Thin Film LaAlO3 Substrates Overview
Lanthanum aluminate (LaAlO3), commonly abbreviated as LAO, is an inorganic compound featuring a distorted perovskite structure. This optically transparent ceramic oxide serves as a high-temperature superconducting single crystal substrate, making it ideal for epitaxial growth of high-temperature superconducting thin films and giant magnetic thin films. Its exceptional dielectric properties are well-suited for low-loss microwave and dielectric resonance applications.
Key Advantages
- Small dielectric constant for enhanced performance
- Low dielectric loss ensuring signal integrity
- Excellent lattice matching capabilities
- Minimal thermal expansion coefficient
- Superior chemical stability
- Wide energy gap characteristics
- Large specific surface area
- Controlled activity levels
- Outstanding thermal stability
