Implication

Predicts high-pressure phases of Al4C3, showing stability peaking at 26 GPa and highlighting unique structural features.

Abstract

We predict that Al 4 C 3 adopts a cubic, anti‑spinel–type structure (Al 4 C 3 -II) between 7 and 33 GPa, peaking in stability relative to other Al 4 C 3 structures at 26 GPa. At ambient pressure, Al 4 C 3 -II is mechanically robust, with...
