Phonon anharmonicity in Cu-based layered thiophosphates
Rahul Rao, Michael A. Susner
In this work, we performed temperature-dependent Raman spectroscopy studies on three layered metal thiophosphates: CuInP2S6, CuCrP2S6, and CuInP2S6-In4/3P2S6 heterostructures. Thes…

Ferrielectric-paraelectric phase transitions in layered CuInP2S6 and CuInP2S6- In4/3P2S6 heterostructures: A Raman spectroscopy and X-ray diffraction study
Rahul Rao, Ryan Selhorst, Benjamin S. Conner +1
CuInP2S6 (CIPS) is an emerging layered material that exhibits ferrielectric ordering well above room temperature (Curie temperature TC ~ 315 K). When synthesized with Cu deficienci…
