The crystallinity and the electrical properties of thin films of the semiconducting polymer poly‐3‐hexylthiophene are investigated on a single layer of graphene by D. R. Barbero and team on page 664. Enhanced vertical charge transport and a much higher charge carrier mobility are measured in thicker films due to the face‐on orientation induced by the graphene substrate and the formation of an interconnected path of crystallites.
