Pressure-tuned plethora of ferroelectric phases in CuInP2S6

Abstract Layered chalcogenides like CuInP2S6 are room temperature ferroelectrics. Modest compression even increases the electric polarization, raising questions about the origin of this unusual trend and other properties under pressure. In this work, we combine synchrotron-based infrared and Raman s...
