Abstract
The adsorption of ethene on Cu(111) has been investigated using LEED, HREELS, TPD and work function measurements (Δφ) at 100 K. Ethene adsorption results in a maximum Δφ value of 0.90 eV. The TPD exhibits a single desorption state with a maximum desorption rate at 120 K. In the vibrational spectrum a dominant energy loss signal at 112 meV is assigned to the out of plane CH 2 wagging mode. No additional diffraction pattern could be observed after ethene adsorption in the entire coverage range.
