(a) Schematic illustration of the experimental set-up for CVD-growth of MoS2; and illustration of temperature profile for the MoS2 growth process at different stages. (b), (c) and (d) show the optical images for as-grown MoS2 monolayer films and isolated monolayer crystallites. (e) Photoluminescence (PL) map of the synthesized MoS2 monolayers and (f) shows the corresponding Raman intensity map. The synthesized MoS2 were grown on SiO2/Si substrates. (g) Experimental results show the PL spectrum of MoS2 films. Inset, typical Raman spectra collected from the area of the MoS2 monolayer film. (h) and (i) SEM images of carbon cloth surface before and after CVD process; (j) and (k) SEM images show large crystals can be found on carbon cloth surface; (l) Raman spectrum taken from the pristine carbon cloth and the one after CVD synthesis.
