Abstract
The high pressure phase transitions of InAs1-xSbx /InSb and InAs1-xSbx/InAs superlattices are investigated using Raman spectroscopy. Both component layers of the superlattices undergo a phase transition at the same pressure. In the InAs1-xSbx/InAs system, this pressure is the same as that of bulk InAs, independent of the Sb content of the alloy layer. In the InAs1-xSbx/InSb system, the transition pressure is either that of the InAs1-xSbx alloy, or it is the mean of the transition pressures of both constituent layers. The mechanisms which could cause the differences in transition pressures are discussed
