摘要：

High-resolution electron energy loss spectroscopy and thermal desorption spectroscopy have been applied to the study of the adsorbed state of benzene molecules on the Si(111) (7 x 7) surface. Both physisorbed and chemisorbed states were found at 90 K. Physisorbed benzene is desorbed by heating to almost-equal-to 200 K; chemisorbed benzene 315 and almost-equal-to 325 K. It is proposed that benzene in the chemisorbed state is pi-bonded to the Si(111) surface.
