Magnesium Oxide Single Crystal Substrate Description

Magnesium Oxide (MgO) Single Crystal Substrate is widely used in many thin film technology fields. For example, it is used to make magnetic thin films, semiconductor thin films, optical thin films, and high-temperature superconducting thin films. The dielectric constant and loss of MgO single crystal in the microwave band are very small. Magnesium Oxide Single Crystal Substrate is a large area substrate, and it is one of the important high-temperature superconducting thin film single crystal substrates for current industrialization. It can be used to make high-temperature superconducting microwave filters and other devices required for mobile communication equipment.
