Low-coverage of EDOT monomers on Cu(110) self-organize into stacks. (A) STM image showing stacks of EDOT molecules on Cu(110) subsequent to a five-minute DIEDOT exposure [V = -365 mV, I = 1.0 nA, (8.9 nm)²]. The surrounding bare regions of the Cu(110) substrate exhibit a (1 × 1) symmetry. The positions of the molecules in the stack are shown, as calculated by DFT viewed from (B) the front and (C) the top. The model shows Cu atoms lifted out of the top substrate layer to participate in bonding to the EDOT.
