Sr2GeO4
Sr2GeO4 is a thermodynamically stable, wide-gap insulating oxide composed of strontium, germanium, and oxygen.
About Sr2GeO4
Sr2GeO4 is a thermodynamically stable oxide compound that sits firmly on the convex hull, indicating significant structural robustness. As a wide-gap insulator, it possesses electronic properties characteristic of materials that resist electrical conduction, making it a subject of interest for fundamental materials research.
Its structural versatility is highlighted by the existence of multiple distinct crystalline phases reported in databases. This diversity in structural arrangements allows researchers to investigate how atomic coordination influences the physical behavior of strontium germanates in various technological contexts.
Key Properties
Cross-validated computational properties for Sr2GeO4, 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.
