This substrate requires material matching to the target thin-film or device workflow. All specification parameters must be verified before use.
- Material Matching: Confirm that the substrate material and crystal family match the target thin-film or device workflow before quotation.
- Specification Verification: Verify orientation, dimensions, thickness, polishing condition, and offcut details for the selected option.
How does the lattice constant of the GGG (100) substrate influence thin film epitaxy, and what is the specified value?
The GGG (100) substrate has a cubic lattice constant of a = 12.380 Å. This value is critical for lattice matching with the target thin-film material. The product note explicitly advises confirming that the substrate material and crystal family match the target thin-film workflow to avoid defects from lattice mismatch.
What are the critical parameters to verify when selecting a GGG (100) substrate for a specific thin-film deposition process?
Key parameters include the substrate material (GGG/Gd3Ga5O12), crystal structure (cubic), orientation (100), surface finish (SSP), dimensions (5×5×0.5 mm or 10×10×0.5 mm), purity (99.99%), and lattice constant (12.380 Å). The product note emphasizes material matching and specification review before quotation.
What are the key physical properties of GGG single crystal substrates that affect handling and processing conditions?
GGG has a density of 7.09 g/cm³, hardness of 6.5 Mohs, and melting point of approximately 1750–1800°C. These properties indicate the substrate is dense, relatively hard, and can withstand high-temperature processing typical of thin film deposition. Care should be taken to avoid thermal shock and mechanical damage.
This GGG (100) single crystal substrate with SSP finish offers a high-purity cubic lattice for epitaxial growth, available in 5×5×0.5 mm and 10×10×0.5 mm options, but requires careful material compatibility validation and is limited to 0.5 mm thickness.
Positive
- High purity and well-defined lattice constant for epitaxial growth: With 99.99% purity and a cubic lattice constant of 12.380 Å, this substrate provides a consistent crystalline template for thin-film deposition, minimizing lattice mismatch and defect propagation in device layers.
- Excellent thermal and mechanical stability: The melting point of 1750-1800°C and Mohs hardness of 6.5 indicate that the substrate can withstand high-temperature processing and mechanical handling without significant degradation.
Trade-offs
- Requires careful material compatibility assessment: The substrate material and crystal family must be confirmed to match the target thin-film or device workflow before quotation, as mismatched lattice parameters or thermal expansion coefficients can compromise film quality.
- Fixed thickness of 0.5 mm for available options: The selectable specification options are limited to 0.5 mm thickness; applications requiring thicker substrates for mechanical support or different thermal mass may not be accommodated by these standard sizes.
