From: Novel polymer-free iridescent lamellar hydrogel for two-dimensional confined growth of ultrathin gold membranes

Figure 4

(a) Transmission electron microscopy (scale bar, 1 μm), (b) Scanning electron microscopy (scale bar, 1 μm), and (c) High-resolution transmission electron microscopy images (scale bar, 2 nm) and (inset) selected-area electron diffraction pattern of a typical Au membrane. (d) Topological atomic force microscopy image (scale bar, 1 μm) and (inset) height profile of a typical Au membrane showing the thickness of 5.1 nm. (e) Transmission electron microscopy image (scale bar, 200 nm) and (inset) enlarged image taken at the folded edge of a typical Au membrane where the naked thickness of the Au membrane is obtained by measuring the width of the folded edge to be 3.6 nm.
