Figure 2.
Raman spectra of the exfoliated TMD samples. Panels (a–c) are the Raman spectra of the exfoliated MoS2, MoSe2 and MoTe2 samples. The characteristic vibration modes of the sample (A1g and E2g) corresponding to their out-of-plane and in-plane vibrations, seen as peaks in the spectra have been labelled for the respective TMDs.
