SrLaAlO4 (Strontium Lanthanum Aluminate) Crystal Wafers
Perovskite Structure: Shares similarities with SrTiO3 but offers a more stable structure with fewer defects.
Lattice Match: Excellent compatibility with high-temperature superconductors like Yttrium Barium Copper Oxide (YBCO), facilitating the growth of high-Tc superconducting films.
Thermal Expansion: Lower thermal expansion coefficients compared to other perovskite crystals, which improves lattice matching and reduces stress during film growth.
Dielectric Properties: Low dielectric constants make it superior for microwave and high-frequency applications.
Applications: High-Temperature Superconductors, Microwave and High-Frequency Devices, Epitaxial Growth, Advanced Material Research, etc.
