Fig. 2.

(a) Low energy electron diffraction pattern of CuPc/Au(1 1 0) as measured. (b) Surface supercell deduced from LEED. The red rectangle symbolizes the unit cell of the unreconstructed Au(1 1 0), whereas black rectangle shows the 5 × 3 unit cell of the overlayer. Here and in the following we choose the x axis along the substrate's [1 − 1 0] direction, and the y axis parallel to the [0 0 1] direction.
