FIG. 1.

(Color online) (a) Test jig is simply a rigid frame with a square recess machined out of graphite and a “piston” mounted on a fine-pitch screw to apply compressive strain. The sample is placed in the recess flush with a smooth sidewall and compressed; the magnitude of the strain is measured by noting the number of turns of the screw. (b) Optical image of the buckled surface of a Pt film ( thick) on PDMS with buckling wavelength ; scale bar . (c) Scanning electron micrograph of nanoporous gold leaf with ligament size ; scale bar . (d) Optical image of the buckled surface of nanoporous gold leaf on PDMS; scale bar .

FIG. 2.

(Color online) Plot of effective Young’s modulus of nanoporous gold leaf as a function of ligament size. The modulus in GPa is plotted on the axis and ligament size in nanometers on the axis; error bars mark one standard deviation in the data. Data points for 100 and ligament NPG from Refs. 9 and 10 are also marked.
