Nb:SrTiO3
SrTiO₃ is one of the most widely used high temperature superconducting single crystal substrates. It is well matched with the lattice of high temperature superconducting materials such as YbACuO, has no twin structure, and has good physical and mechanical properties. Meanwhile, it is also widely used in special Optical windows and high-quality sputtering targets.
