Image of FIG. 1.
FIG. 1.

[(a) and (b)] STM images of the ZnO(0001) surface recorded at and −1.5 V, respectively. (c) Height difference between images [(a) and (b)]; dotted circles indicate typical regions where the contrast is enhanced due to local electronic structure inhomogeneities. (d) Same as (c) including a contour plot of the local roughness. Red contours surround regions where the local surface roughness (standard deviation calculated over a area) on (a) is below 9 pm.

Image of FIG. 2.
FIG. 2.

(a) Mapping of the LDOS at on the same area as in Fig. 1. (b) curves measured at the location of the circles in (a) [also reproduced in Fig. 1(a)]. (c) profile along the dotted line in (a).

Image of FIG. 3.
FIG. 3.

(a) Atomically resolved STM image (, ). [(b) and (c)] Fourier transforms of the areas inside the rectangles drawn in (a).
