Magnesium oxide (MgO) single crystal substrates are widely used in many thin film technology fields. Such as the production of magnetic films, semiconductor films, optical films and high-temperature superconducting films. Because the dielectric constant and loss of MgO single crystal in the microwave band are very small, and large-area substrates (2 inches in diameter and larger) can be obtained, it is an important high-temperature superconducting thin-film single crystal substrate for the current industrialization. one. It can be used to make high-temperature superconducting microwave filters and other devices required by mobile communication equipment, and has a large realistic and potential application market.
