What is the optical transmission range of the MgO (100) single crystal substrate?
The MgO (100) substrate exhibits >90% transmission from 200-400 nm in the UV and >98% transmission from 500-1000 nm in the visible to near-infrared, making it suitable for UV-Vis-NIR optical and spectroscopic applications.
What is the lattice constant of the MgO (100) substrate and how does it affect thin film epitaxy?
The lattice constant is 4.216 Å with a cubic crystal structure. This value is critical for lattice matching with materials such as certain perovskites or oxides; a close match minimizes misfit dislocations during epitaxial growth, directly impacting film quality.
What are the key physical properties of this MgO substrate that influence handling and processing?
The substrate has a Mohs hardness of 5.5, density of 3.58 g/cm³, and a melting point of 2850°C. Its thermal expansion coefficient of 12.8×10⁻⁶/°C should be considered when designing thermal cycles to avoid stress-induced cracking during deposition or annealing.
This MgO (100) single crystal substrate with DSP finish offers high optical transmission from UV to NIR ( >90% at 200-400 nm, >98% at 500-1000 nm) and a cubic lattice constant of 4.216Å, suitable for thin-film epitaxy and optical applications. Available in 5×5×0.5 mm and 10×10×0.5 mm sizes.
Positive
- High optical transmission across UV-NIR: Exhibits >90% transmission from 200-400 nm and >98% from 500-1000 nm, enabling use in UV and visible-near-IR spectroscopy and optics.
- High melting point and cubic structure: Melting point of 2850°C and cubic crystal structure with lattice constant 4.216Å support epitaxial thin-film growth at elevated temperatures.
Trade-offs
- Limited standard size options: Only two standard dimensions (5×5×0.5 mm and 10×10×0.5 mm) are offered, which may restrict sample geometry for certain experimental setups.
- High thermal expansion coefficient: Thermal expansion coefficient of 12.8×10^-6 /C can induce thermal mismatch stress with deposited films having lower expansion coefficients.
