摘要：

We have investigated vibrational modes of C-60 monolayer firm adsorbed on the Si(111)7 x 7 surface using high-resolution electron-energy-loss spectroscopy in combination with scanning tunneling microscopy. The differences in energies and in oscillator strengths from a thick C-60 film (i.e., bulk C-60) ace discussed in terms of the charge transfer from silicon dangling bonds to C-60 molecules. The amount of charge transfer is estimated to be 1+/-1 electron(s) compared with the infrared absorption spectra of alkaline-doped C-60 fullerides and with the weak electron-molecular-vibration coupling calculation.
