This substrate requires confirmation of material compatibility with the target thin-film or device workflow. The selected specification—including orientation, dimensions, thickness, and polishing condition—must be reviewed before use.
- Material Compatibility: Confirm that the substrate material (MgO) and crystal family match the target thin-film or device workflow before quotation.
- Specification Review: Verify orientation (111), dimensions, thickness, polishing condition (DSP), offcut details, quantity, and any custom requirements for the selected option.
What are the key differences between the 5×5×0.5 mm and 10×10×0.5 mm specification options for the MgO (111) DSP substrate?
Both options share the same orientation (111) and surface finish (DSP) with identical material properties, including a cubic crystal structure, lattice constant of 4.216 Å, and optical transmission >90% at 200–400 nm. The choice is purely dimensional: the 5×5×0.5 mm size is suited for smaller-scale or cost-sensitive experiments, while the 10×10×0.5 mm size provides a larger area for multi-sample deposition, as listed in the available specifications table.
What thin-film materials are compatible with the MgO (111) substrate for epitaxial growth?
The MgO (111) substrate has a cubic crystal structure with a lattice constant of 4.216 Å, making it suitable for epitaxial growth of thin films with similar lattice parameters, such as certain perovskites or oxides. The (111) orientation is particularly useful for hexagonal or trigonal film growth. The product description emphasizes confirming material matching with the target thin-film or device workflow before quotation, and recommends contacting technical sales for material matching support.
What physical properties of the MgO (111) substrate are relevant to handling and thermal processing?
The MgO (111) substrate has a density of 3.58 g/cm³, Mohs hardness of 5.5, melting point of 2850°C, and a thermal expansion coefficient of 12.8×10⁻⁶/°C. These values indicate moderate mechanical strength and high thermal stability, which are important considerations for cutting, cleaving, and thermal cycling during deposition or annealing processes.
Atomfair's MgO (111) DSP single crystal substrate offers high optical transparency from UV to NIR and excellent thermal stability for high-temperature thin-film deposition, but its moderate hardness and limited size options require careful handling and application-specific size validation.
Positive
- High UV-Vis-NIR transmittance: Optical transmission exceeds 90% in the 200–400 nm range and 98% in the 500–1000 nm range, making it suitable for transparent substrate applications in optoelectronics and spectroscopy.
- High-temperature stability and cubic symmetry: Melting point of 2850°C and cubic lattice structure (a=4.216 Å) provide a stable platform for high-temperature thin-film epitaxy, especially for (111)-oriented growth.
Trade-offs
- Moderate scratch resistance: Mohs hardness of 5.5 indicates the substrate is susceptible to surface scratching during handling and processing, requiring careful cleaving and cleanroom protocols.
- Limited standard size options: Only two standard dimensions (5×5×0.5 mm and 10×10×0.5 mm) are available, which may restrict compatibility with larger wafer processing equipment or non-standard sample geometries.
