title: Study of the initial adsorption state of tetracene on [Formula: see text].
abstract: Tetracene on the [Formula: see text] surface has been investigated by ultraviolet photoemission spectroscopy (UPS). The UPS results show features, from tetracene, between 2.0 and 10.0 eV below the Fermi level, and their shift in binding energy with increasing coverage. Angle-resolved UPS (ARUPS) results indicate that the molecular plane of tetracene near the interface is parallel to the substrate. Moreover, an ab initio calculation has also been carried out to determine the favourable adsorption structure. Temperature-dependent UPS measurements show that tetracene is stable on the [Formula: see text] surface up to 150 °C.
