Cr1Hf2Ir1
Cr1Hf2Ir1 is a semiconducting ternary alloy containing chromium, hafnium, and iridium that exists in a metastable state.
About Cr1Hf2Ir1
Cr1Hf2Ir1 is a complex ternary alloy categorized within the platinum-group metal systems. It exhibits semiconducting electronic behavior, which distinguishes it from the typical metallic nature of many related transition metal alloys. Its structural diversity is evidenced by numerous reported configurations, highlighting its complexity in solid-state chemistry. Due to its position above the thermodynamic stability hull, this compound is considered metastable. This characteristic makes it a subject of significant interest for researchers investigating the synthesis of non-equilibrium phases and the potential for tuning electronic properties through structural manipulation.
Key Properties
Cross-validated computational properties for Cr1Hf2Ir1, 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.
