TmN
TmN is a stable semiconducting compound formed from thulium and nitrogen that is frequently studied for its structural and electronic properties.
About TmN
TmN is a binary compound consisting of thulium and nitrogen. As a member of the rare-earth nitride family, it exhibits semiconducting behavior and maintains high thermodynamic stability, placing it directly on the convex hull of its constituent elements. Its structural versatility is highlighted by the multiple distinct crystalline arrangements reported in scientific databases.
This material is of significant interest for researchers investigating the intersection of magnetism and semiconducting properties in rare-earth compounds. Its stability makes it a robust candidate for fundamental studies into electronic band structures and potential applications in specialized electronic or magnetic devices.
Key Properties
Cross-validated computational properties for TmN, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
