Two dimensional ferroic materials exhibit a variety of functional propertiesthat can be tuned by temperature and pressure. CuInP2S6 is a layered materialthat is ferrielectric at room temperature and whose properties are a result ofthe unique structural arrangement of ordered Cu and In cations within a P2S6anion backbone. Here, we investigate the effect of hydrostatic pressure on thestructure of CuInP2S6 single crystals through a detailed Raman spectroscopystudy. Analysis of the peak frequencies, intensities and widths reveals fourhigh pressure regimes. At 5 GPa the material undergoes a monoclinic-trigonalphase transition. At higher pressures (5 - 12 GPa) we see Raman peaksharpening, indicative of a change in the electronic structure, followed by anincommensurate phase between 12 - 17 GPa. Above 17 GPa we see evidence formetallization in the material. The original state of the material is fullyrecovered upon decompression, showing that hydrostatic pressure could be usedto tune the electronic and ferrielectric properties of CuInP2S6.
