“…2 displays three distinct molecular features: the first one-labeled hybridization state-appears very close to the Fermi level at an average binding energy of about 0.4 eV. In analogy to PTCDA/Ag(1 1 1) [21,22,26], it results most likely from the population of the p * -like lowest unoccupied molecular orbital by transferred electrons from the Ag 4s states, maybe including the electrons from the Shockley states [24]. Although this state is partially filled, we call it briefly LUMO or former LUMO in the following.…”
