Self‐alignment of lamellar nanodomains is accomplished by imposing thickness modulation to a block copolymer thin film. Real‐time atomic‐force microscopy imaging reveals that the self‐alignment occurs through the directional growth of well‐aligned domains along thickness gradients. This novel self‐aligning principle, based on a “geometric anchoring” phenomenon, is reported by S. O. Kim, O. D. Lavrentovich and co‐workers on page 2584 .
