Stability of CrSi 2 grown from the melt

Research output: Contribution to journalArticlepeer-review


In a recent paper it was shown that density-functional calculations predicted that a putative C11 b crystal structure of CrSi 2 should be more stable than the observed C40 structure. This echoes the situation in SiC, where cubic stacking at the surface is favored over the stable bulk hexagonal structure. To investigate these similarities further, calculations have been done on stacking faults at the surface of CrSi 2. These show that while the surface energy of C40 is lower than C11 b, this is not sufficient to account for its stability. ©2005 The American Physical Society.
