(a) LEEM image of irregularly shaped structures of 6P grown on the Ir{111} surface. The Ir{111} surface appears dark and the ramified 6P islands show different shades of grey. (FoV: 15 μm, electron energy: 3.5 eV, deposition temperature: 320 K) (b) μLEED pattern obtained from one of the islands at an electron energy of 19.4 eV. The nearest neighbor cell is highlighted by red lines. (c) The structural model proposed from the μLEED pattern shown in (b). The molecules are arranged in up-right standing orientation on Ir{111}. Nearest neighbor cell, unit cell and the 5×5 superstructure are indicated by red lines (solid, dashed, and dotted respectively).
