Niobium-doped strontium titanate has a similar structure to pure strontium titanate single crystal, but Nb:SrTiO3 has electrical conductivity. The conductive Nb:SrTiO3 substrates provide an electrode for certain thin film and device applications. At present, we can provide Nb:SrTiO3 single crystal substrates with Niobium doping concentration of: 0.1wt%, 0.5wt%, 0.7wt% and 1.0wt%. OST Photonics offers high quality Nb:...
