“…However, in contrast to these well-established bulk properties, the chemical and structural properties of its interface with metals have not yet been explored in detail. The (111)-surfaces of the coinage metals Au, Ag, and Cu cover a wide range of reactivity and, therefore, emerged as model systems to study the contact formation with OSCs such as pentacene [26][27][28][29], perylene [30][31][32], coronene [33][34][35][36], diindenoperylene (DIP) [37][38][39][40], perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) [35,[41][42][43][44], or 6,13-pentacenequinone (P2O) and 5,7,12,14-pentacenetetrone (P4O) [45][46][47]. In the present paper, we performed a systematic study of the ELA and molecular surface structure of TAT adsorbed on Au(111), Ag(111), and Cu(111) by combining inverse photoelectron spectroscopy (IPES), ultraviolet photoelectron spectroscopy (UPS), and x-ray photoelectron spectroscopy (XPS) with low energy electron diffraction (LEED) and the x-ray standing wave (XSW) technique.…”
