Al1Hf2Re1 is a semiconducting ternary compound consisting of aluminum, hafnium, and rhenium that is currently considered a metastable phase.
About Al1Hf2Re1
Al1Hf2Re1 is a complex ternary compound composed of aluminum, hafnium, and rhenium. As a semiconducting material, it occupies a distinct niche in solid-state chemistry, drawing interest from researchers investigating the electronic properties of transition metal-based alloys.
Despite its existence in a significant number of reported structural configurations, this compound is characterized by its position above the thermodynamic hull. This suggests that while it can be synthesized or modeled, it remains a metastable phase that offers insights into the intricate phase space of these specific metallic elements.
Key Properties
