| 英文摘要 | The electronic structures of fullerene/metal interface are critical to the performance of devices based on fullerene in molecular electronics and organic electronics. herein, we investigate the electronic structures at the interface between c-84 and ag(111) by photoelectron spectroscopy and soft x-ray absorption spectroscopy techniques. it is observed that c-84 monolayer on ag(111) surface (1-ml c-84/ag(111)) has metallic nature. a charge transfer from substrate to the unoccupied states of c-84 is determined to be 1.3 electrons per molecule. however, the work function of 1-ml c-84 (4.72 ev) is observed slightly larger than that of the clean ag(111) substrate (4.50 ev). a bidirectional charge transfer model is introduced to understand the work function variation of the fullerene/metal system. in addition to the charge transfer from substrate to the adsorbate's unoccupied states, there exists non-negligible back charge transfer from fullerene occupied molecular orbital to the metal substrate through interfacial hybridization. the fermi level will be pinned at similar to 4.72 ev for c-84 monolayer on coinage metal substrate.
