Fig. 1. (a) Schematic of the intercalation process. The S atoms are intercalated between the TMdC and Au layers, under an S-rich atmosphere, at 600 °C. Confocal Raman mapping images of (b) as-grown and (c) intercalated WS2 grains, for 2LA(M) mode intensity. (d) and (e) Representative Raman spectra extracted from regions I–IV in (b) and (c).
