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…
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…
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…
Insights into carbon nanotube nucleation: Cap formation governed by catalyst interfacial step flow
Rahul Rao, Renu Sharma, Frank Abild-Pedersen +2
In order to accommodate an increasing demand for carbon nanotubes (CNTs) with desirable characteristics one has to understand the origin of helicity of their structures. Here, thro…
