· Be3N2

Be₃N₂ is a wide-bandgap semiconductor compound belonging to the beryllium nitride family, featuring a lightweight ceramic structure with high elastic stiffness. This material remains largely experimental and is pursued primarily in research settings for high-temperature and high-frequency electronic applications, where its extreme thermal stability and wide bandgap could theoretically outperform conventional semiconductors like GaN or SiC; however, manufacturing challenges and beryllium toxicity concerns have limited practical deployment compared to more mature wide-bandgap alternatives.
