CrMo
CrMo is a metallic binary alloy of chromium and molybdenum that exhibits a wide array of structural possibilities despite its thermodynamic instability.
About CrMo
CrMo is a binary metallic compound composed of chromium and molybdenum. As a metallic system, it exhibits characteristic electron delocalization and conductivity typical of transition metal alloys. Its structural landscape is remarkably diverse, with a high volume of reported configurations across various databases.
Despite the significant number of identified structures, the compound sits above the thermodynamic hull, suggesting it is metastable or unstable under standard conditions. This makes it a subject of interest for researchers studying phase formation and the complex interplay between alloying elements in transition metal systems.
Key Properties
Cross-validated computational properties for CrMo, 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 CrMo. 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.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
