Description

MgO Wafer (111) (100) Polished Magnesium oxide Monocrystal Semiconductor Customized

Description of MgO Wafer:

Single crystal MgO wafers are a staple of thin film labs for supporting high-quality oxide (and metal) epitaxial thin film growth including semiconducting, superconducting, dielectric, ferroelectric, and ferromagnetic oxides. MgO crystals grow nicely with minimal defects meaning it is available up to 2 inch diameter and as a high hardness material can be polished with near atomic-scale roughness (rms <0.2 nm).
Due to its high transparency (even at 0.5 mm thick >85%), it is often used for optical experiments to investigate the film on top, in which case select the double side polished if doing these measurements in transmission mode.

The Character of MgO Wafer:

Electrical Insulation: MgO wafers exhibit excellent electrical insulation properties, making them suitable for use in electronic devices and insulating layers in semiconductor applications.
Thermal Stability: MgO wafers have high thermal stability and can withstand high temperatures, which is advantageous for applications requiring heat resistance.
Optical Transparency: In certain wavelengths, MgO wafers demonstrate good optical transparency, making them useful in optoelectronic applications such as LEDs and laser diodes.
Hardness: MgO wafers are characterized by their high hardness, which contributes to their durability and resistance to wear and abrasion.
Chemical Inertness: MgO wafers are chemically inert and resistant to corrosion, enhancing their suitability for use in harsh environments and chemical processes.
Crystal Structure: MgO wafers typically have a cubic crystal structure, which can impact their physical and optical properties.
Dielectric Properties: MgO wafers exhibit favorable dielectric properties, making them suitable for use in capacitors and other electronic components.
Magnetic Properties: In certain configurations, MgO wafers can exhibit magnetic properties, which are beneficial for applications in magnetic tunnel junctions and magnetic storage devices.

FAQ:

1.Q: What is magnesium oxide substrates?
A: Magnesium Oxide Single Crystal Substrate is used to make magnetic films, semiconductor films, optical films, high-temperature superconducting films, etc.
2.Q: How do you clean MgO substrate?
A: Magnesium Oxide Single Crystals absorb moisture which will damage the surface of the crystals. To protect the polish from moisture, ESPI packages the material under dry argon gas. To clean the crystals, soak in alcohol, preferably methanol. The crystals should be held in this solution until ready for film growth.
