Cover: The article by Potemkin and coworkers provides free‐energy considerations to explain the molar mass dependent morphology of lamellar diblock copolymer thin films of poly(styrene‐ b ‐butadiene). Atomic force microscopy (AFM) and grazing‐incidence small‐angle scattering (GISAXS) data were instrumental to establish the lamellar orientation as a function of the interaction parameter χN and the ratio of film thickness over lamellar thickness D red . The relevant free‐energy contributions are discussed that determine the boundary between the observed orientational phases. Further details can be found in the article by I. I. Potemkin, * P. Busch, D.‐M. Smilgies, D. Posselt, and C. M. Papadakis on page 579.
