Electronic properties of the F16CuPc molecule-gold interface: Spectroscopic signature of ultra-fast charge delocalization
Original language description
Understanding the charge transfer process at organic/metal interfaces is crucial, as it affects the efficiencies of organic electronics and photovoltaic devices. To this aim, in situ, synchrotron radiation-based photoemission and near-edge X-ray absorption fine structure (NEXAFS) combined with resonant photoemission spectroscopies (RPES) spectra were used to study the interaction and alignment of the adsorbed F16CuPc molecules on Au (111) substrate. The polarization-dependent NEXAFS reveals that F16CuPc molecules were lying flat on the Au (111) surface at both the sub-monolayer and multilayer coverages. The core-level photoemission findings suggest that an interfacial layer was formed at the molecule-Au interface for an interfacial interaction. Moreover, the molecules remained nearly flat with a small deformation, staying in close contact with the substrate. In addition, employing the core-hole clock technique, the ultrafast interfacial charge transfer time was around 12 fs at the interface of the F16CuPc thin film and the Au (111) substrate. Our results consequently provide valuable insights into the charge transfer process of a photo-excited n-type molecule on a metal surface, which will help open a new direction for the realization of the F16CuPc for organic electronic devices.
