Figure 2

(a) Scanning electron and (b) optical microscopy images of monolayer 2DP suspended over a copper grid and deposited on 300 nm SiO2/Si, respectively. (c) Atomic force microscopy (AFM) image of the monolayer 2DP on 300 nm SiO2/Si. (d) Selected area electron diffraction (SAED) pattern of the monolayer 2DP sandwiched by two layers of graphene (G), G/2DP/G. (e) Molecular structure of the monolayer 2DP predicted by DFTB calculation. (f) AFM, and (g,h) TEM images of a multilayer 2DP synthesized at liquid–liquid interface. The insert in h is a SAED pattern of the multilayer. (i) Photographic image of monolayer 2DP on 4-inch 300 nm SiO2/Si wafer. Scale bar, 100 μm (a); scale bar, 100 μm (b); scale bar, 3 μm (c); scale bar, 2 nm−1 (d); scale bar, 3 μm (f); scale bar, 50 nm (g) and scale bar, 3 nm (h), respectively.
