SrTiO₃ (Strontium Titanate) single crystal is a high-quality perovskite oxide material extensively used as a substrate for epitaxial growth of complex oxide thin films. Owing to its well-defined cubic perovskite structure, excellent lattice matching, and atomically smooth surface, SrTiO₃ is a benchmark substrate in superconductivity, ferroelectricity, multiferroics, dielectric materials, and oxide electronics research. SrTiO₃ offers a high dielectric constant, good thermal stability, and excellent chemical compatibility with a wide range of oxide materials. These properties make it ideal for advanced thin-film deposition techniques such as PLD (Pulsed Laser Deposition), MBE, sputtering, and ALD, where precise lattice matching and surface quality are critical for achieving high-performance epitaxial layers. Our SrTiO₃ single crystal substrates are manufactured with strict control of crystallographic orientation, thickness uniformity, and surface flatness. Precision polishing ensures low surface roughness suitable for atomic-scale film growth, enabling reproducible and reliable results for both fundamental research and device prototyping. Multiple orientations and custom sizes are available to support diverse experimental requirements, including large-area substrates with diameters up to 35 mm. Custom specifications, including thickness, orientation, and surface finish, can be provided upon request.
