This substrate requires confirmation of material compatibility with the intended thin-film or device workflow prior to use. Orientation (111) and surface finish SSP must be verified against the specific deposition or growth requirements.
- Material Matching: Confirm that the gadolinium gallium garnet crystal family and lattice constant (12.380 Å) are compatible with the target thin-film or device workflow.
- Specification Verification: Verify that the selected orientation (111), surface finish SSP, dimensions, thickness, and any offcut details match the requirements of the intended application.
What is the lattice constant of the GGG (111) single crystal substrate and why is it important for epitaxial thin film growth?
The GGG (111) substrate has a cubic lattice constant of 12.380 Å (Z=8). This parameter is critical for evaluating lattice mismatch with target thin-film materials, directly influencing epitaxial quality and defect density. The value is specified in the product datasheet and is a standard consideration for oxide thin film deposition workflows.
What is the purity and crystal quality of the Atomfair GGG (111) substrate, and how does it affect research reproducibility?
The substrate is grown by the Czochralski method and has a purity of 99.99%, with a cubic crystal structure. These specifications ensure high crystalline integrity and low impurity levels, which are essential for reproducible thin film growth and device performance in research applications.
What are the key physical properties of the GGG substrate that affect handling, processing, and storage?
The substrate has a density of 7.09 g/cm³, hardness of 6.5 Mohs, melting point of approximately 1750-1800°C, and a refractive index of 1.95. All available specifications have a thickness of 0.5 mm, making the substrates fragile. Careful handling with clean tweezers and storage in a clean, dry environment is recommended to avoid breakage and surface contamination.
Gadolinium Gallium Garnet (111) single crystal substrate with SSP finish, available in three sizes, offering 99.99% purity and Czochralski-grown low defect density, but requiring careful lattice matching and limited to (111) orientation and SSP polish.
Positive
- High purity and Czochralski growth: 99.99% purity and Czochralski method ensure low defect density, suitable for high-quality epitaxial film deposition.
- Multiple substrate sizes available: Available in 5×3, 5×5, and 10×10 mm dimensions with 0.5 mm thickness, accommodating various sample holder and experiment geometries.
Trade-offs
- Fixed orientation and polish: Only (111) orientation and SSP surface finish are offered, limiting use for applications requiring other crystallographic orientations or polish types.
- Lattice matching requirement: The cubic lattice constant (12.380Å) must be matched to the target thin-film material to avoid strain; pre-quotation material matching is essential.
