Nanoscale materials fatigue within a single 7 Å layer of a 2D nano‐layered material, muscovite mica, resembles fatigue in macroscopic systems except for two remarkable properties: first, there is an Å‐scale precision in the depth of the damage and second, there are sharply defined “magical” stresses, beyond yield, at which the surface remains intact regardless of the number of applications of stress.
