The above AFM analyses get support from TEM studies. Once again, numerous flakes with smooth surface and well-resolved edges are observed (Figure 8a and SI: Section VI). The folded structure arrowed in Figure 8a, reflecting the characteristics that a 2D graphene sheet tends to fold to obtain the thermodynamic stability through static microscopic crumpling,54 is
