NbTc
NbTc is a thermodynamically stable metallic alloy formed from niobium and technetium.
About NbTc
NbTc is a binary metallic compound composed of niobium and technetium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these transition metals.
Its metallic nature suggests high electrical conductivity, making it an interesting subject for fundamental research into transition metal alloys. With extensive structural data available across multiple databases, it serves as a well-documented reference point for understanding the interplay between these specific elements.
Key Properties
Cross-validated computational properties for NbTc, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of NbTc. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
