Notes:
We report on a systematic study of the thin-film growth and the electronic structure of the intrinsic molecular semiconductor lutetium–diphthalocyanine (LuPc2). The films were grown in ultrahigh vacuum. Starting from submonolayer coverage, thickness-dependent x-ray and ultraviolet photoemission spectroscopy (UPS) measurements have been carried out. Information about the growth mechanism, the work function, and the evolution of the valence density of states with increasing coverage have been obtained. By combination of UPS with high-resolution electron-energy-loss spectroscopy an assignment of the spectroscopic structures to recently published molecular-orbitals calculations is proposed.
