Figure 2: (a) Large-scale STM image of the DBT adlayer in 1-octanoic acid. Tunneling parameters: = 570 pA and = 820 mV. (b) High-resolution STM image of the DBT adlayer. Tunneling parameters: = 570 pA and = 820 mV. (c) Structure model for the DBT adlayer. Possible hydrogen bonds are shown in the enlarged inset by black dashed lines.
