SrTiO3

SrTiO3

Breif intruduction of SrTiO3 single crystal substrate

SrTiO3 single crystal  has good lattice structure the same as the perovskite structure material.

It is a kind of good substrate material.

Has been widely used in high temperature superconducting thin film research, but also widely used in the special optical window and the high quality of sputtering target materials.
