Neodymium Doped Strontium Titanate Substrate (Nd: SrTiO3)
Neodymium Doped Strontium Titanate Substrate
Neodymium doped Strontium titanate (Nd: SrTiO3) single crystal has a similar structure to SrTiO3 crystal, which matches well with the lattice of perovskite structure materials. The substrates are widely used for the epitaxial growth of various oxide films. We provide 0.05% Nd-doped concentration for Nd: SrTiO3 single crystal substrate.
