HN2P
HN2P is a thermodynamically stable, insulating hydride compound investigated for its potential utility in hydrogen storage technologies.
About HN2P
HN2P is a hydrogen-rich compound classified within the hydrogen storage hydrides family. As a wide-band-gap insulator, it exhibits distinct electronic characteristics that differentiate it from metallic or semi-metallic storage candidates, contributing to its fundamental interest in materials science.
This material is noted for being thermodynamically stable on the convex hull, suggesting a robust structural framework. Its existence across multiple databases highlights its status as a subject of ongoing computational investigation for potential applications in solid-state hydrogen containment.
Key Properties
Cross-validated computational properties for HN2P, 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.
