(color online) The self-assembled behaviors of single-layer DAT molecules on Au (110) at different growing conditions. (a) Schematic diagram and (e) large-scale STM image of the original Au (110) surface without molecular deposition. (b), (c), and (d) Schematic diagrams of the Au (110) surface with monolayer DAT molecules after annealing the sample at 100 °C, 200 °C, and 350 °C, respectively, and (f), (g), and (h) the corresponding large-scale STM images of the sample, respectively. The scanning conditions are −0.50 V, 0.1 nA in panel (e), −1.15 V, 0.1 nA in panel (f), −0.60 V, 0.1 nA in panel (g), and −1.22 V, 0.1 nA in panel (h), respectively.
