Vibration analysis of Graphene embedded in ordered fluids using Raman spectroscopy

POSTER

Abstract

We studied the vibrational characteristics of both single- and multi-layered Graphene embedded in liquid crystal (LC), possessing various ordered phases, by polarized micro-Raman spectroscopy. The evolution of the vibrational modes (G and 2D bands) was studied in 8CB in the isotropic, nematic and smectic A phases. The shifts in the vibrational modes are discussed in the context of the phase transition in the LC system.
