In this work X-ray photoemission spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) are employed to study the CuPc/Al(1 0 0) organic–inorganic interface.

Abstract
In this work X-ray photoemission spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) are employed to study the CuPc/Al(1 0 0) organic–inorganic interface. The C 1s core level, investigated for three different coverages, shows sharp differences in passing from bulk to monolayer range CuPc film: in particular the shake-up satellite is not visible in the early stages of adsorption, suggesting a strong molecule–substrate interaction. XAS at the Cu L3 edge was employed to study the molecular orientation with respect to the substrate. In the case of a 40Å CuPc film the molecular plane was found to be almost perpendicular to the substrate surface.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
