Crystro Thin Film Substrates Lanthanum Aluminate LaAlO3 Crystal
Crystro Thin Film Substrates LaAlO3 ( Lanthanum aluminate) Wafer Substrates
Introduction :
LaAIO3 is a high temperature superconducting single crystal substrate. It is well-matched with YBaCuO high-temperature superconducting thin film materials in a lattice with lower dielectric constant, low loss microwave. The dielectric properties of LaAlO3 crystal are well suitable for high-temperature superconducting microwave electronic devices.
Main Features :
- good chemical stability
- Good lattice match to most materials with Perovskite structure
- Low dielectric constant
- Low microwave loss
Applications :
- High-Temperature Superconducting, magnetic, and ferroelectric thin films
- Low loss microwave applications
- Dielectric resonance applications
