Starting from real grown crystals and their habit the binding energies of a molecule for different crystal directions are estimated and some ideas about the electronic surface morphology are given. The high concentration of lattice defects on the surface causes their interaction which leads to a quasicontinuous energetic distribution of traps. The microstructure of the distribution can be referred to the geometry of the crystal lattice. The theoretical results agree excellently with the experiments.
