· LiMgN

LiMgN is a ternary nitride semiconductor compound combining lithium, magnesium, and nitrogen. This material remains largely in the research and development phase, explored for wide-bandgap semiconductor applications where its light-element composition and nitride chemistry offer potential advantages in optoelectronic and high-temperature device environments. The material family shares characteristics with other III-V and II-VI nitrides, positioning it as a candidate for next-generation wide-bandgap electronics where conventional semiconductors reach performance limits.
