· JVASP-134138· Be2Se

Be₂Se is a beryllium selenide ceramic compound belonging to the II–VI semiconductor family, characterized by a zinc-blende crystal structure. While primarily explored in research and advanced materials development rather than high-volume production, this material is investigated for optoelectronic and photonic applications where its wide bandgap and optical transparency in the infrared spectrum offer potential advantages. Engineers consider Be₂Se compounds in specialized contexts such as radiation-hard semiconductors, infrared windows, and high-energy physics detectors where chemical stability and thermal properties are critical, though material availability and the toxicity profile of beryllium limit widespread industrial adoption compared to alternative selenides.
