semiconductor· Sr1 B6
Strontium hexaboride (SrB₆) is a ceramic compound belonging to the rare-earth hexaboride family, characterized by a cubic crystal structure and metallic-like electrical properties. It is primarily investigated for thermionic emission applications and high-temperature electronics, where its combination of thermal stability and electron-emitting capabilities offers advantages over traditional tungsten cathodes in vacuum tubes and electron guns. The material is notable for its relatively low work function and chemical inertness at elevated temperatures, making it of particular interest in research contexts for next-generation electron sources and specialized vacuum device applications.
