Abstract

The adsorption structure of a single C2 H2 molecule on a Cu(111) surface was analyzed by scanning tunneling microscopy (STM) and inelastic tunneling spectroscopy (IETS). The STM result showed a twofold rotational symmetry, in agreement with the structural model previously proposed. The IETS spectrum measured near a monatomic step exhibited peaks related to the C-H stretch mode, which were as strong as what had been reported for C2 H2 on a Cu(100) substrate, where the amplitude of the electronic standing wave that causes background fluctuation of spectra could be considerably reduced by the reduction of scattering at the step. Chemical reactions induced by electron injection were also observed by IETS analysis near steps.
