MgO (Magnesium Oxide Crystals), due to its low dielectric constant and minimal microwave band loss, along with the availability of large-sized wafers (up to 2 inches in diameter and larger), has emerged as a crucial industrial material for High-Temperature Superconductor (HTS) thin monocrystalline wafers. MgO serves as an exceptional single-crystal substrate catering to various thin film growth tasks including Ferro-magnetic, Photo-electronic, semiconductor, and high-temperature superconductor films. Its utility extends to III to V element research, exploring epitaxial effects on polymer crystallization, and even for depositing ferroelectric coatings on its substrates. Moreover, MgO wafers find increasing applications in Plasma Display Panel (PDP) technology.
Hangzhou Shalom EO provides both stocked standard MgO wafers and customized wafers.
