Figure 4

(a) XRD pattern of the nanobelts. (b) A TEM image of a nanobelt. (c, d) A HRTEM taken from the edge of the nanobelt and corresponding FFT pattern. (e) A STEM image taken from the tip of a nanobelt. (f–h) EDS maps for Au, Gen and Se, respectively. Scale bar: 100 nm. (i) A STEM image of the nanobelt. Scale bar: 1 μm. (j, k) EDS profiles taken along the red and green arrows in (i), respectively.
