SrTiO3 Monocrystal Substrate
SrTiO3 single crystal has the good lattice structure possessed by perovskite structure materials. For the epitaxial growth of HTS and most oxide films, it is an excellent substrate material and has been widely used in the research of high-temperature superconducting films. It is also widely used in special optical windows and high-quality sputtering targets.
