Electronic excitation of ice monomers on Au(111) by scanning tunneling microscopy
Scanning tunneling microscopy, inelastic tunneling spectroscopy, and electron induced manipulation are used to investigate electronic excitation of D2O monomers and small clusters adsorbed at the elbows of the Au(111) reconstruction. Diffusion of molecules, dissociation of clusters, and rearrangement of the reconstruction is induced by electronic excitation. Threshold energies of between 200 and 250 meV and of 446 meV are explained by combined vibrational modes of D2O molecules. External vibrational modes of D2O molecules on Au(111) are identified by inelastic tunneling spectroscopy at ≈18, 30, and 41 meV.
