Abstract

X-ray and ultra-violet photoemission spectroscopies (XPS and UPS) reveal strong interaction between Ca and tris-(8-hydroxy quinoline) aluminum (Alq₃) during the Ca/Alq₃ interface formation. The details of the interaction depend on the direction of the interface formation. For the Ca on Alq₃ case, Ca interacts with the N groups before attacking the O groups in Alq₃. The UPS spectra point to the emergence of new states in the energy gap. However, when depositing Alq₃ on Ca, the entire molecule appears to undergo a significant decompositional reaction. In contrast, no interaction occurs between Alq₃ and the Ca substrate if it is first passivated by an oxygen pretreatment.
