This single crystal substrate requires material matching to the target thin-film or device workflow. Orientation tolerance, surface roughness, and lattice constant impose constraints on epitaxial growth quality.
- Material Matching: Confirm that the selected YSZ substrate material and (111) crystal orientation match the target thin-film or device workflow before quotation.
- Orientation Tolerance: The substrate orientation tolerance of ±0.5° must be considered for epitaxial growth alignment.
- Surface Roughness: The surface roughness of less than 5 Å is critical for achieving high-quality thin-film interfaces.
- Lattice Constant: The lattice constant of 5.125 Å should be matched to the deposited film's lattice parameter to minimize strain.
What is the surface roughness of the YSZ (111) single crystal substrate and how does it affect thin film growth?
The surface roughness is less than 5Å, as specified for the single-side polished (SSP) finish. This ultra-smooth surface minimizes nucleation defects and is ideal for high-quality epitaxial deposition of thin films requiring atomically flat interfaces.
What is the orientation tolerance of the (111) YSZ substrate and why is it critical for device fabrication?
The orientation tolerance is ±0.5°, ensuring consistent crystallographic alignment across the substrate. This precision is critical for applications such as oxide heterostructures or superconducting films where lattice registry directly impacts electronic properties.
How does the arc melting growth method affect the crystal quality and purity of YSZ substrates?
The arc melting method yields a cubic single crystal with 99.99% purity and a lattice constant of 5.125Å. This process produces substrates with low defect density and high thermal stability, with a melting point of 2800°C, making them suitable for high-temperature processing.
Yttria-stabilized zirconia (YSZ) single crystal substrate with (111) orientation, single side polished, available in 10×10×0.5 mm and 5×5×0.5 mm sizes. Offers high purity (99.99%), low surface roughness (<5 Å), and high thermal stability (melting point 2800°C) for demanding thin-film deposition and high-temperature epitaxial growth.
Positive
- High purity and ultra-low roughness: Crystal purity of 99.99% and surface roughness <5 Å minimize interfacial defects and scattering, critical for high-quality thin-film epitaxy and device fabrication.
- Exceptional thermal stability: Melting point of 2800°C and thermal expansion coefficient of 10.3×10⁻⁶/°C enable compatibility with high-temperature deposition and annealing processes without substrate degradation.
Trade-offs
- Single side polish only: SSP (single side polished) surface finish limits optical transmission or back-side reflectivity applications that require double-side polishing; back-side scattering may affect certain measurements.
- Fixed size selection range: Only two standard sizes (10×10×0.5 mm and 5×5×0.5 mm) are offered, which may not accommodate custom substrate dimensions required for non-standard sample holders or multi-chip integration.
