Magnesium selenide (MgSe) is a II-VI semiconductor ceramic compound combining a lightweight alkaline-earth metal with a chalcogen element. While primarily a research material rather than a commodity engineering ceramic, MgSe belongs to the wider family of binary semiconductors studied for optoelectronic and photovoltaic applications, offering potential advantages in wide bandgap device design where its optical and electrical properties may provide tailored performance.
