Material & Engineering Overview
Precision-grown and chemical-mechanical-polished (CMP) in a Class 100 cleanroom, our lanthanum aluminate (LaAlO3) Single-Crystal substrates (LaAlO3, CAS 12003-65-5) substrates provide atomically smooth, epi-ready surfaces (Ra < 0.2–0.5 nm) for thin-film epitaxy, pulsed laser deposition (PLD), magnetron sputtering, molecular beam epitaxy (MBE), and optical characterization.
Czochralski-grown LaAlO3 combines a pseudocubic perovskite lattice (a = 3.791 Å) with low microwave dielectric loss tangent (tan δ ~ 3 × 10⁻⁵), making it ideal for high-frequency superconducting filters and functional oxide epitaxy. Standard research sizes include 5×5 mm, 10×10 mm, and 15×15 mm diced squares (0.5 mm or 1.0 mm thick) as well as Ø 1-inch, 2-inch, 3-inch, and 4-inch wafers in single-side (SSP) or double-side (DSP) polished finishes, packed in individual waffle trays or nitrogen-sealed cassettes with batch orientation and surface inspection data.

Technical & Procurement FAQ
Are lanthanum aluminate (LaAlO3) Single-Crystal substrates (LaAlO3) substrates ready for epitaxial deposition out of the box?
Yes. All epi-ready substrates are final CMP-polished and packaged in cleanroom waffle packs or sealed containers with sub-nanometer Ra roughness.
What tolerances apply to 10×10×0.5 mm diced LaAlO3 substrates?
Standard lateral dimensions are ±0.05–0.10 mm, thickness is ±0.02–0.05 mm, and crystal axis orientation accuracy is within ±0.5° (or ±0.1° on custom request).
Can I order custom sizes, thicknesses, or double-side polishing for TB-SUB-LAO?
Yes. Both single-side (SSP) and double-side (DSP) polished substrates as well as custom laser/wire-saw diced dimensions can be quoted with no high minimum order quantity.
