· LiZnAs

LiZnAs is a ternary ceramic compound combining lithium, zinc, and arsenic elements, belonging to the broader family of III-V semiconductors and intermetallic ceramics. This material is primarily of research interest rather than established commercial use, being studied for potential optoelectronic and photonic device applications due to its semiconductor properties and crystal structure. Its inclusion in materials databases reflects ongoing investigation into wide-bandgap semiconductors and compound ceramics for next-generation electronic and photonic applications where conventional materials reach performance limits.
