LaTaO4
LaTaO4 is a thermodynamically stable, wide-band-gap insulating perovskite oxide used in materials science research for its dielectric potential.
About LaTaO4
LaTaO4 is a stable member of the perovskite oxide family, characterized by its robust electronic structure as a wide-band-gap insulator. Its presence on the convex hull signifies high thermodynamic stability, which is a critical attribute for materials intended for long-term functional use in demanding environments. This compound is frequently studied for its potential in electronic and optical applications where insulating behavior is paramount. The material exhibits significant structural diversity, as evidenced by multiple reported crystallographic configurations across major databases. This structural flexibility allows researchers to tune its properties for specific technological integration, positioning it as a versatile candidate in the broader landscape of complex oxide materials.
Key Properties
Cross-validated computational properties for LaTaO4, aggregated across 4 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 perovskite oxides class.
Unlike the metallic or semi-metallic behavior often found in transition-metal-rich perovskites like LaNiO3, LaTaO4 is defined by its wide-gap insulating nature, placing it closer to the dielectric characteristics of LaAlO3 rather than the magnetic or conductive profiles of LaMnO3 or LaCoO3.
