SrTiO3 Substrate

SrTiO3 single crystal provides a good lattice match to most of the materials with Perovskite structure. It is an excellent substrate for the epitaxial film of HTS and many oxides. It has been used widely for special optical windows and as high quality sputtering target. OST Photonics offers high quality SrTiO3 substrates for researchers and industries. Crystal orientation, size and thickness can be customized accordi...
