Figure 2

TEM images of the prepared graphene sheets. Samples are prepared at an optimum oleylamine/toluene ratio, which are monolayer, few-layer, and single-layer graphene sheets with a curved edge, (a, b, c) respectively. (d) Selected area electron diffraction (SAED) pattern corresponding to (a) with peaks labeled by the Miller-Bravais (hkil) indices. HRTEM images of the edge (e) and in-plane (f) of the graphene sheet taken from (a).
