(color online) Shear strain distributions over the nano-single crystal specimen. Strain data in panels (a) and (b) are extracted from the four fixed line regions in Fig. 3(c) at different coordinate values (pixels). Strain data in panels (c)–(e) are acquired through counting the strains of all the atoms in Figs. 3(a)–3(c), respectively, and the red solid line is the Gaussian profile.
