Back in black : All metastable and stable phases can be identified for the solid solution arsenic/phosphorus by a combination of quantum‐chemical calculations and investigations of the phase formation. Reaction paths for phase formations and transitions in situ were also evaluated. The results show that orthorhombic black arsenic ( o ‐As) is metastable in pure form and has only been previously obtained by stabilizing impurities.
