Joint-PDF of the K ions for (a) sample (I) at the z = 0 section, (b) sample (I) at z = 1/2, (c) sample (II) at z = 0, (d) sample (II) at z = 1/2, (e) sample (III) at z = 0 and (f) sample (III) at z = 1/2. Contour intervals are 0.02 atom Å−3. Broken lines indicate the zero level. Note that the origin (0 0 0) is locally not the maximum, but the minimum in maps (a), (c) and (e). Maximum densities in these maps are observed at the four equivalent positions displaced close to the origin. In (b), (d) and (f), the center position (x, y) = (0, 0) has the maximum density. |
