Abstract

The surface structure of C₂H₄ on Si(001) has been investigated by coaxial impact collision ion scattering spectroscopy (CAICISS). To determine the adsorption structure of the C₂H₄ molecules definitely, the computer simulation with the two-dimensional trajectory count method has been applied to the recently proposed most possible two single molecular adsorption configurations (di-σ on-top and di-σ end-bridge). The CAICISS spectra and simulation results show that the di-σ on-top structure is better fitted with the experimental results rather than the di-σ end-bridge.
