Revealing the KH2PO4 soft-mode coupling mechanism with infrared spectroscopy under pressure

D. Santos-Cottin, S. Nasrallah, F. Capitani +4

We measured the far-infrared reflectivity of a KH2PO4 single crystal up to pressures of 2 GPa in the ferroelectric and paraelectric phases. We find that the nu4 vibrational mode of…
