Raman scattering of single crystal Cu2MoS4 nanosheet

Polarized Raman spectra were recorded under parallel and perpendicular configurations in back scattering geometry for a single crystal Cu2MoS4 nanosheet of c-plane (001) faced orientation. The angular dependence of Raman peaks intensity for different phonon modes were studied by rotating from 0 to 180 degree around the c-axis of the ternary layered crystal. In combination with the theoretical calculations, the experimentally observed Raman peaks were assigned to four active Raman modes accordingly. (C) 2015 Author(s).
