Breif intruduction of MgO Mgnesium Oxide Single Crystal Substrate

In the current industry, it is an important high-temperature superconducting thin film of single-crystal substrates.

As it is in the microwave band dielectric constant and loss are small, and can obtain a large area of a substrate (a diameter of 2 inches and larger).

Branch crystal company arc discharge using a special high purity growth size of about 2 “x2” x 1 “, low-cost single crystal MgO, prepared by chemical mechanical polishing the surface of high quality substrates atomically.
