LiAlFeO4
LiAlFeO4 is a semimetallic, metastable layered lithium transition-metal oxide used primarily in fundamental materials science research.
About LiAlFeO4
LiAlFeO4 is a complex lithium transition-metal oxide characterized by a near-zero-gap electronic structure. As a member of the layered oxide family, it represents a multifaceted inorganic material that has been documented across multiple structural databases, reflecting significant interest in its potential configurations.
Due to its position above the thermodynamic hull, this compound is considered metastable, posing challenges for traditional synthesis. Its unique composition of lithium, aluminum, iron, and oxygen makes it a subject of fundamental research into the electronic behavior of transition-metal oxides.
Key Properties
Cross-validated computational properties for LiAlFeO4, 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.

How It Compares
Within the layered lithium transition-metal oxides class.
Unlike the highly stable and commercially ubiquitous LiCoO2 or the spinel-structured LiMn2O4, LiAlFeO4 exhibits a semimetallic character and lacks the robust thermodynamic stability found in its more common class siblings. While materials like LiAlO2 are often utilized for their structural stability, LiAlFeO4 remains a more experimental candidate within the layered oxide group.
