Raman spectroscopy study of lattice vibration and crystallographic orientation of monolayer MoS2 under uniaxial strain

The false-color (3D type) image of the intensity of the Raman spectra of monolayer MoS2 versus both peak positions and polar angles is plotted. It shows that the strongest E2g1+ and E2g1− peaks appear at different angles, reflected as the alternation of the maxima of the intensity within the frequen...

Raman spectroscopy study of lattice vibration and crystallographic orientation of monolayer MoS2 under uniaxial strain
description The false-color (3D type) image of the intensity of the Raman spectra of monolayer MoS2 versus both peak positions and polar angles is plotted. It shows that the strongest E2g1+ and E2g1− peaks appear at different angles, reflected as the alternation of the maxima of the intensity within the frequency range of the E2g1 mode, which is the consequence of the crystallographic orientation relevant to the strain direction as predicted by theoretical analysis.
