Unpinning and snapping back of pillars. Notice the increased deflection of the neighboring pillars each time a pinned pillar was released and jumped back to its initial position. Due to high nucleation density and corresponding frequent coalescence of dewetting holes, we observed unpinning events only for group A pillars in the 2NP scenario. The labels L and R stand for “left” and “right” pillar. At \(R/\omega \approx\) 1.25: no unpinning of pillars yet. At \(R/\omega \approx\) 1.30: unpinning of pillar L. At \(R/\omega \approx\) 1.35: additional unpinning of pillar R. The length of the black bar represents 10 μm.
