Investigating strain between phase-segregated domains in Cu-deficient CuInP2S6
Rahul Rao, Ryan Selhorst, Jie Jiang +6
CuInP2S6 (CIPS) is an emerging layered ferroelectric material with a TC above room temperature. When synthesized with Cu deficiencies (i.e., Cu1-xIn1+x/3P2S6), the material segrega…
Pressure-Induced Insulator-to-Metal Transition in van der Waals compound CoPS
Takahiro Matsuoka, Rahul Rao, Michael A. Susner +3
We have studied the insulator-to-metal transition and crystal structure evolution under high pressure in the van der Waals compound CoPS through electrical r…
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…
Strength of the dominant scatterer in graphene on silicon oxide
Jyoti Katoch, Duy Le, Simranjeet Singh +3
A large variability of carrier mobility of graphene-based field effect transistors hampers graphene science and technology. We determine the scattering strength of the dominant sca…
Probing the Electrical Properties of Overlapped Graphene Grain Boundaries by Raman spectroscopy
Rahul Rao, Neal Pierce, Avetik R. Harutyunyan
The effect of grain boundaries and wrinkles on the electrical properties of polycrystalline graphene is pronounced. Here we investigate the stitching between grains of polycrystall…
