SrLaI5
SrLaI5 is a metastable semiconducting iodide compound currently under investigation for its structural complexity and electronic properties.
About SrLaI5
SrLaI5 is a complex iodide compound characterized by its semiconducting electronic nature. As a metastable material, it represents a unique structural configuration that challenges conventional thermodynamic stability, making it a subject of significant interest for researchers mapping the landscape of ternary halide systems. Its existence across multiple reported structures suggests a rich potential for structural phase transitions and tunable properties. Because of its specific elemental composition, this compound is primarily investigated within fundamental materials science to understand the interplay between strontium and lanthanum in halide frameworks. It serves as a model system for exploring how metastable phases can be stabilized or utilized in specialized electronic or optical applications where traditional, highly stable materials may not offer the desired performance characteristics.
Key Properties
Cross-validated computational properties for SrLaI5, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
