J. Buisset et al., ADSORBATE SITE DETERMINATION WITH THE SCANNING TUNNELING MICROSCOPE -C2H4 ON CU(110), Physical review. B, Condensed matter, 54(15), 1996, pp. 10373-10376
Scanning tunneling microscopy at T=4 K has been used to determine dire
ctly the binding site of a molecule chemisorbed on a metal surface, na
mely, ethene on Cu{110}, by simultaneous imaging of the adsorbate and
the underlying lattice. The molecule is found to bond in the short bri
dge site on the close-packed rows with its C-C axis oriented in the [1
10] direction.
