10mm Square SrTiO3 Crystal Wafer For Semiconductor
SrTiO3 single crystal has the good lattice structure of perovskite structure materials. For the epitaxial growth of HTS and most oxide films, SrTiO3 single crystal is an excellent substrate material. It has been widely used in the study of high temperature superconducting thin films, and also widely used in special optical Windows and high quality sputtering targets.
