Figure 1

(a) Filled-state images of pyridazine adsorbed on a clean Ge(100) surface. The yellow arrows mark the uniform orientation of clover features with three leaves. Bias: −2.0 V. (b) Zoomed-in clover features in the green rectangle in a. The zigzag chains in b and d sketch the up Ge dimer atoms of Ge(100). (c) A clover feature at a bias of −0.5 V. (d) A lucky-clover feature with four leaves on a dimer row. Bias: −2.0 V. Tunnelling current for all images: 300 pA. Scale bar, 4 nm.
