Figure 3
Holographic reconstruction of CuAu in the plane perpendicular to the φ rotation axis and cutting through a fluorescing Cu atom. The reconstructed atomic intensity is shown in a linear grey scale (darker for higher intensity) without background cut-off. The coordinate origin is the position of a fluorescing Cu atom. The square with solid lines has a side length of the actual lattice constant, 3.75 Å, and the dashed lines are crossed at the centre of the square. They are drawn in order to indicate the actual positions of atoms. |
