Fig. 1: Experimental results of a membrane irradiated with dose of 2.4 · 1011 pJscm−2 per point.
From: Ultrastiff graphene

AFM images showing the membrane a before and b after optical forging. Panels c and d show 3D-rendered images of a and b with the same colorscale. Raman spectra e and force curves f showing the graphene before (black) and after (red) forging. Note that in panels c and d the vertical dimension is sixfold enhanced compared to the lateral dimension. Scale bars are 1 µm.
