LAO (LaAlO3) Lanthanum Aluminate Crystal Substrate (111) 5x5x0.5 mm FAQs

Q1: What are the key material properties of LAO (LaAlO3) Lanthanum Aluminate Crystal Substrate (111) 5x5x0.5 mm?

A1: LaAlO3 (LAO) is a single-crystal oxide with a rhombohedral perovskite structure that becomes pseudocubic above around 435°C. It has a relatively low lattice mismatch with many functional perovskite thin films, making it an excellent substrate choice. The lattice parameter is approximately 3.79 Å, and it exhibits good thermal stability, a moderate dielectric constant (~24), and a thermal expansion coefficient close to that of typical perovskites.

Q2: How should this product be handled and stored to prevent damage or contamination?

A2: Because LAO substrates are inherently brittle and can fracture under stress, they should be handled with clean, lint-free gloves and precision tweezers to avoid contamination or scratches. Keep them away from harsh chemicals and avoid temperature shocks that can induce cracks. Store substrates in dust-free containers or wafer cassettes under low-humidity conditions, and regularly inspect them for any surface contaminants prior to thin film deposition.

Q3: Which quality standards and certifications apply to LAO (LaAlO3) Lanthanum Aluminate Crystal Substrate (111) 5x5x0.5 mm?

A3: LaAlO3 (111) substrates are typically manufactured under ISO 9001:2015 quality management to ensure consistent orientation accuracy, dimensional precision, and surface smoothness. They often follow SEMI guidelines for crystal orientation and wafer geometry. X-ray diffraction is commonly used to verify crystal quality, while atomic force microscopy checks surface roughness at sub-nanometre levels, delivering high repeatability and reliability for advanced epitaxial growth.
