Product Description:
Overview: Nb-doped Strontium Titanate (Nb:SrTiO₃) crystals maintain the structural integrity of pure SrTiO₃ while introducing electrical conductivity via Niobium doping. These conductive substrates are used for providing internal electrodes in thin-film heterostructures and electronic device fabrication. The material is twin-free and available in various doping concentrations to meet specific resistivity requirements.
