a STM image of surface prepared by annealing for 10 min at 650 C. 550 × 350 nm2, I = 0.2 nA, U = 1.8 V. Inset: LEED pattern of the ZnO(\(10\bar{1}4\))-surface (52 eV) with the surface unit cell marked by the dashed rectangle. b STM image of the as prepared ZnO(\(10\bar{1}4\)) surface. 80 × 50 nm2, I = 0.2 nA, U = 1.8 V. Dotted squares: type (i) defects, dash-dotted ovals: type (ii) defects. c Line scan across several terraces along the line indicated (a). Averaged over 20 nm. Dashed lines indicate the determined average height between terraces: 1.2 Å. d Line scan perpendicular to the steps along the line indicated in b. Dashed lines indicate the average step periodicity of 13.1 Å.
