Identification of individual and few layers of WS(2) using Raman Spectroscopy

The Raman scattering of single- and few-layered WS(2) is studied as a function of the number of S-W-S layers and the excitation wavelength in the visible range (488, 514 and 647 nm). For the three excitation wavelengths used in this study, the frequency of the A(1g)(Γ) phonon mode monotonically decr...
