Product Description
Lanthanum Aluminum Oxide Substrate (LaAlO3)
LaAlO3 is a high-temperature superconducting single crystal substrate ideal for epitaxial growth of high-temperature superconducting thin films and giant magnetic thin films. Its superior dielectric properties make it particularly suitable for low-loss microwave and dielectric resonance applications.
Key Advantages
- Small dielectric constant with minimal dielectric loss
- Excellent lattice matching capabilities
- Low thermal expansion coefficient
- Superior chemical stability
- Wide energy gap with large specific surface area
- High thermal stability with controlled activity
