a Raman spectra as a function of the layer number of samples. 532 nm laser was used as the excitation source. The plotted region has the strongest Raman signal. The Raman spectrum down to ~120 cm−1 is included in Supplementary Fig. 4. b White light reflection contrast spectroscopies as a function of the layer number. Samples for this measurement were exfoliated onto transparent, fused silica substrates.
