Figure 7: Applications of crack.
From: Universality of periodicity as revealed from interlayer-mediated cracks
(a) Optical dark-field image of demonstration of crack protection by using closed loop crack pattern. Outer random cracks (indicated by white arrows) are stopped by pre-existing closed loop crack. The scale bar represents 100 μm. (b) Cross-sectional SEM image of a metal nanowire template demonstration. Pt 100 nm was evaporated through the crack gap. Scale bar represents 1 μm.
