Heterointerfaces of organic semiconductors can show high electrical conductivity, but the details of their electronic structure remain largely unexplored. Schottky-gated heterostructures have now been used to probe the interface between single crystals of rubrene and PDIF-CN2, showing that charge transport is due to electrons whose mobility exhibits band-like behaviour down to ~150 K.
