摘要：

We present results of pseudopotential calculations for the high-pressure phases of indium antimonide, showing that the recently observed Cmcm superlattice structure is the most stable crystal structure at high pressure. Furthermore, we show that the competing high-pressure phases observed in this and other III-V semiconductors can be characterized into a hierarchy by ordering and topology and that symmetry is a secondary characteristic in determining the energy.
