This substrate requires careful material matching to the target thin-film or device workflow. The orientation, dimensions, thickness, and surface finish must be confirmed before procurement.
- Material Matching: Confirm that the substrate material and crystal family match the target thin-film or device workflow to ensure compatibility.
- Orientation and Surface Finish: The (110) orientation and SSP surface finish are fixed specifications that must be verified for the intended application.
- Specification Review: Verify the selected dimensions, thickness, polishing condition, and offcut details prior to quotation.
What is the optical transmission of MgO (110) substrates across UV and visible wavelengths?
The MgO (110) single crystal substrate exhibits >90% transmission in the UV range (200–400 nm) and >98% transmission in the visible to near-IR range (500–1000 nm). These values are specified directly from the product data and make the substrate suitable for in-situ optical monitoring during thin-film deposition or for UV-Vis spectroscopy applications.
What is the lattice constant of MgO (110) single crystal substrates and how does it affect thin film growth?
The MgO (110) substrate has a cubic crystal structure with a lattice constant of a = 4.216 Å, as stated in the technical specifications. This lattice parameter is a critical factor for epitaxial growth of thin films requiring close lattice matching, such as certain perovskite oxides, and must be confirmed against the target film material to minimize strain and defects.
What are the thermal and mechanical properties of MgO substrates relevant to high-temperature thin film deposition?
The MgO substrate has a melting point of 2850°C, a thermal expansion coefficient of 12.8 × 10⁻⁶ /°C, a density of 3.58 g/cm³, and a Mohs hardness of 5.5. These properties, taken directly from the product data, indicate stability at high processing temperatures but also require careful handling due to moderate hardness to avoid scratching or chipping during substrate mounting and transfer.
Magnesium Oxide (110) single crystal substrate with SSP surface finish offers high optical transmission (>90% UV, >98% Vis-NIR) and thermal stability up to 2850°C, but requires careful handling due to Mohs hardness 5.5 and material matching verification for thin-film compatibility.
Positive
- High optical transmission: Optical transmission >90% in the 200-400 nm range and >98% in the 500-1000 nm range, enabling efficient UV-Vis-NIR spectroscopic and photonic applications.
- High thermal stability: Melting point of 2850°C and low thermal expansion coefficient of 12.8 × 10⁻⁶/°C provide structural integrity under high-temperature processing conditions.
Trade-offs
- Moderate hardness requires care: Mohs hardness of 5.5 makes the substrate susceptible to surface scratches during handling, polishing, or cleaning, requiring careful laboratory protocols.
- Material matching required: The substrate material and crystal family must be explicitly confirmed to match the target thin-film or device workflow, adding a qualification step before procurement.
