(color online) The comparison of DAT molecular structures in the Au (110)-(1×3) reconstruction after annealing the monolayer sample at 200 °C and 350 °C, respectively. (a) and (b) High-resolution STM images of DAT molecules in (1 × 3) reconstruction after annealing at 200 °C and 350 °C, respectively. (c), (d), (e), and (f) Structural models and simulated STM images of two types of DAT molecules in (1 × 3) reconstruction after the annealing, respectively. The scanning conditions are −1.15 V, 0.1 nA in panel (a) and −1.22 V, 0.1 nA in panel (b), respectively.
