More info

Strontium Titanate (SrTiO3) Crystal Substrate is a high-quality perovskite oxide material with a well-matched lattice structure, making it suitable for high-temperature superconductor (HTS) thin films and oxide film applications. Its atomically smooth surface allows precise layer-by-layer epitaxial growth, with controlled termination between TiO2 and SrO atomic planes. It is also used in optical windows and sputtering targets. Besides, we also offer Nd:SrTiO3, Fe:SrTiO3, and Nb:SrTiO3 substrates for specialized applications. Heeger Materials delivers high-quality SrTiO3 Crystal Substrates for research and industry.
