Neodymium doped strontium titanate, Nd-doped SrTiO3 single crystal have a similar structure to SrTiO3. SrTiO3 single crystal has a good lattice structure of perovskite structure material, and is an excellent substrate material, special optical window material and sputtering target for epitaxial growth of HTS and various oxide films. Currently We can provide a Nd concentration: 0.05% Nd: SrTiO3 single crystal substrate
