In a recent study from the Electronic & Magnetic Materials & Devices and Theory & Modeling groups at the Argonne National Laboratory, C60 and pentacene (Pn) molecules, two workhorses of organic electronics and opto-electronics, are observed to self-assemble on a Cu(111) surface into in-plane "pinwheel"-shaped and chiral heterojunctions. Calculations confirm that the heterostructures are energetically favorable conformations and reveal electron charge transfer from the Pn to the C60 in this chiral morphology, a critical signature of electronic heterojunctions.
