摘要：

Cobalt phthalocyanine (CoPc) monolayer films evaporated on Au-(100) are studied by photoexcited electron spectroscopies: X-ray absorption (XAS) and resonant Photoemision Spectroscopy (ResPES) According to XAS data the Co 2p absorption spectra look different for monolayer and thicker organic films, pointing to a possible interaction of the molecules with the substrate via the Co d electrons. The contribution of Co-related states in the valence band of CoPc was observed with ResPES. The conclusions are discussed in combination with core level X-ray photoemission spectroscopy (XPS), X-ray excited Auger electron spectroscopy (XAES), and valence band ultraviolet photoemission spectroscopy (UPS) results previously obtained.
