a Topography of a single molecule on the free surface. b Same topography as a, but with shifted color scale. The white arrow indicates a surface defect. c–h Differently sized molecular clusters on the free terrace. i Molecules clustering at a step edge. Inset: single molecules attached to a step edge. All scale bars have a length of one nanometer. Tunneling parameters: a–e Ubias = 1 V, Iset = 50 pA. f Ubias = −1 V, Iset = 50 pA, h–i Ubias = 0.4 V, Iset = 50 pA, inset i Ubias = 1 V, Iset = 50 pA.
