K4Pt2
K4Pt2 is a thermodynamically stable semiconducting alloy composed of potassium and platinum.
About K4Pt2
K4Pt2 is a distinct member of the platinum-group alloy class, characterized by its semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement within the potassium-platinum binary system.
This compound is of significant interest to materials scientists investigating the electronic tuning of noble metal alloys. Its stability and semiconducting nature make it a valuable subject for understanding how alkali metals modify the catalytic potential of platinum-group elements.
Key Properties
Cross-validated computational properties for K4Pt2, 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.
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.
