Material matching between the substrate and the target thin-film or device workflow must be confirmed before quotation. The substrate orientation and crystal family must be compatible with the intended application.
- Material Matching Requirement: Confirm that the selected substrate material and crystal family match the target thin-film or device workflow before quotation.
What is the optical transmission of the MgO (110) substrate across UV to near-IR wavelengths?
The MgO (110) substrate exhibits >90% transmission from 200-400 nm and >98% from 500-1000 nm, making it suitable for UV and visible-light applications as stated in the product specifications.
What is the lattice constant of the MgO (110) substrate, and how does it affect thin-film epitaxial growth compatibility?
The MgO substrate has a cubic crystal structure with a lattice constant of 4.216 Å. This parameter is critical for selecting lattice-matched materials such as certain perovskites and oxides; however, specific matching must be confirmed for the target thin-film workflow.
What is the thermal expansion coefficient of the MgO (110) substrate, and why is it important for high-temperature processing?
The thermal expansion coefficient is 12.8 × 10⁻⁶ /°C. This value is essential for minimizing thermal stress during deposition or annealing when combined with materials having different expansion coefficients, ensuring substrate and film integrity at elevated temperatures.
This MgO (110) single crystal substrate with DSP surface finish offers high optical transmission (>90% in UV, >98% in visible-NIR) and a melting point of 2850°C, making it suitable for high-temperature and optical thin-film applications. Its moderate Mohs hardness (5.5) and thermal expansion coefficient (12.8×10⁻⁶/°C) require careful handling and material matching to avoid mechanical or thermal stress issues.
Positive
- Broad spectral transparency: Optical transmission >90% from 200–400 nm and >98% from 500–1000 nm, enabling efficient UV-to-NIR operation in optical and photonic devices.
- High melting point: With a melting point of 2850°C, the substrate withstands high-temperature deposition and annealing processes without degradation.
Trade-offs
- Moderate mechanical hardness: Mohs hardness of 5.5 makes the substrate susceptible to scratches and surface damage during handling, requiring careful cleanroom protocols.
- Thermal expansion mismatch consideration: Thermal expansion coefficient of 12.8×10⁻⁶/°C may differ from common thin-film materials, requiring thermal stress analysis to prevent film cracking or delamination.
