Al1Re2Ta1
Al1Re2Ta1 is a semiconducting ternary intermetallic compound that currently exists as a metastable phase in computational materials databases.
About Al1Re2Ta1
Al1Re2Ta1 is a complex ternary intermetallic compound composed of aluminum, rhenium, and tantalum. Its electronic character is defined as semiconducting, marking it as a distinct subject for researchers investigating the interplay between transition metals and light elements in solid-state systems.
While this material has been identified across multiple structural configurations in computational databases, it is currently characterized as being thermodynamically unstable relative to the ground state. This suggests that its synthesis may require specific non-equilibrium conditions or stabilization techniques to realize its potential in advanced material science applications.
Key Properties
