Figure 2: Optical and AFM images, with associated Raman spectra, for a monolayer WS2 flake before and after transfer.

From: Transfer of monolayer TMD WS2 and Raman study of substrate effects

Figure 2

(a) Optical image of flake, pre-transfer, on growth substrate. (b) AFM image of flake in (a) before transfer. (c) Raman spectrum of flake in (a) showing the characteristic WS2 peaks at 351, 356, and 417 cm−1. (d) Optical image of flake post transfer, on the silicon oxide substrate. (e) AFM of flake in (d). (f) Raman spectrum of the transferred flake in (d) showing the same characteristics peaks as in (c).
