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 essential 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.

Manufacturing Precision:
– Available Orientations: <100>, <110>, <111>
– Orientation Accuracy: ±0.5°
– Edge Orientation Accuracy: 2° (Specialized request: < 1°)
– Specialized Processing: Off-axis/Miscut angles (1° – 45°) available upon request
– Surface Roughness (Ra): ≤ 5 Angstrom (Atomic level flatness)
