Raman spectroscopy is a powerful probe to determine the num- ber of layers in graphene samples. [14–16] The stacking of layers, in particular, canhave stronginfluence onthe electron–phononcoupling of different phonon modes as is evident from the doping- dependent Raman studies of single ...
We mechanically exfoliate mono- and few-layers of the transition metal dichalcogenides molybdenum disulfide, molybdenum diselenide, and tungsten diselenide. The exact number of layers is unambiguously determined by atomic force microscopy and high-resolution Raman spectroscopy. Strong photoluminescence emission...
