What optical and microwave properties does the Dia. 8 x 0.5 mm MgO single crystal substrate provide for thin-film research?

This MgO substrate is specified for optical transmission greater than 90% from 200 to 400 nm and greater than 98% from 500 to 1000 nm, with a dielectric constant of 9.8 and low dielectric constant and loss in the microwave band. These properties support ferroelectric, magnetic, optoelectronic, and high-temperature superconducting thin-film work as well as microwave filter research.

Can this one-side polished MgO wafer be used as an epitaxial substrate, and which lattice parameters are relevant for compatibility?

Yes, the substrate is intended for epitaxy and thin-film preparation. It has a cubic crystal structure with lattice constant a = 4.216 Å, a melting point of 2850°C, and a thermal expansion coefficient of 12.8 x 10^-6 /°C, which are the parameters to evaluate against the deposited film.

What specification and configuration details must be confirmed before ordering the Dia. 8 x 0.5 mm MgO substrate?

This listing is for a one-side polished (SSP), round wafer with dimensions Dia. 8 x 0.5 mm, supplied as 10 pieces per box. Before quotation, confirm Atomfair model AF-MgO-D8S, material, dimensions, orientation, thickness, and surface finish; custom orientation and size requests can also be confirmed for project-specific requirements.

Assessment

This specific MgO single crystal substrate (Dia. 8 × 0.5 mm, SSP) offers high optical transmission (>90% UV, >98% visible-NIR) and low microwave dielectric loss, making it suitable for epitaxial thin-film research in optoelectronics and microwave filters, though its small size and single-side polish limit broader application.

Positive

High optical transmission UV to NIR: Transmission >90% from 200-400 nm and >98% from 500-1000 nm enables sensitive optical characterization and photo-based thin-film deposition monitoring.
Low microwave dielectric loss: Dielectric constant of 9.8 with low loss in the microwave band supports high-quality epitaxial growth for microwave filter and resonator research.

Trade-offs

Single-side polished only: This listing specifies one-side polished (SSP) finish; double-side polished substrates require a separate purchase for applications needing both faces optically smooth.
Small 8 mm diameter wafer: The 8 mm diameter limits sample area and may require specialized handling fixtures or adapters for processing equipment designed for larger standard wafer sizes.
