Fig. 3

Large-scale STM topographs revealing the annealing-induced surface modifications and structural phase changes in the 1.5 ML DBBA on the Au(111) surface at (a) 100 °C, (b) 150 °C, (c) 200 °C, (d) 250 °C, (e) 300 °C, and (f) 350 °C. STM set-parameters are +2 V/10 pA (a–c) and −2 V/10 pA (d–f). Scale bars are 100 nm.
