Figure 4. Orientation-dependent DIC of asymmetric and symmetric 3D AuNS.

Figure 4.

(a) DIC images at different orientations, (b) contrast with fit, and (c) SEM image of an asymmetric 3D AuNS. (d) DIC images and (e) contrast with fit show weak orientation-dependence for a AuNS with nearly 4-fould symmetry (f).
