YAl2N3
YAl2N3 is a metastable ternary nitride semiconductor that serves as a specialized material for exploring advanced electronic and optoelectronic device architectures.
About YAl2N3
YAl2N3 is a complex ternary nitride semiconductor that represents a unique intersection of rare-earth chemistry and group-III nitride materials. Its metastable nature makes it a subject of significant interest for researchers investigating phase stability and structural transformations in non-equilibrium material systems.
As a semiconducting nitride, this compound holds potential for specialized electronic and optoelectronic applications where traditional binary nitrides may not offer the desired band structure or lattice matching. Its existence within multiple reported structural configurations highlights the structural diversity inherent in yttrium-based nitride systems.
Key Properties
