(a) A TEM image of silicon NCs; (b,c) HRTEM of silicon NCs, with lattice fringes corresponding to (220) and (311) planes of silicon; (d) size statistic of silicon NCs from a large number of TEM images. The most probable size of1.91 nm is calculated according to Gaussian fitting, as the curve shows; and (e) XRD line of silicon NCs.
