Niobium-Doped Strontium Titanate Crystal Substrate | Nb:SrTiO3 Substrate

Niobium-Doped Strontium Titanate (Nb:SrTiO3) Crystal Substrate has a structure similar to pure SrTiO3 but offers electrical conductivity, making it useful for various electronic applications. Its resistivity ranges from 0.1 to 0.001 ohm-cm, depending on the doping concentration, which varies from 0.01% to 0.001 wt%. We currently provide Nb:SrTiO3 substrates with niobium doping levels of 0.05%, 0.1%, 0.5%, and 0.7%. These conductive single-crystal substrates serve as electrodes for thin films and electronic devices. Heeger Materials supplies high-quality Nb:SrTiO3 substrates for advanced research and industrial applications.
