Epi-ready CMP-polished strontium titanate (SrTiO3 & Nb:STO) Single-Crystal substrates (SrTiO3 / Nb:SrTiO3, CAS 12060-59-2) wafers and diced research squares with sub-nanometer surface roughness for PVD, PLD, MBE, and ALD.
Precision-grown and chemical-mechanical-polished (CMP) in a Class 100 cleanroom, our strontium titanate (SrTiO3 & Nb:STO) Single-Crystal substrates (SrTiO3 / Nb:SrTiO3, CAS 12060-59-2) 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.
Featuring the canonical cubic perovskite lattice (a = 3.905 Å), SrTiO3 and conductive Nb-doped SrTiO3 (0.05%, 0.5%, 0.7% wt) are foundational substrates for complex oxide MBE/PLD, 2DEG interfaces (LAO/STO), and bottom-electrode ferroelectric stacks. 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.
