About In1Mn1Ti2
In1Mn1Ti2 is a complex ternary intermetallic compound composed of indium, manganese, and titanium. It exhibits a near-zero-gap electronic character, placing it in the category of semimetallic materials that bridge the gap between conductors and insulators.
Due to its position above the thermodynamic hull, this compound is considered metastable, representing a challenging target for experimental synthesis. Its structural complexity is highlighted by the numerous configurations reported across materials databases, reflecting significant interest in its potential phase space.
Key Properties
Cross-validated computational properties for In1Mn1Ti2, aggregated across 2 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.
