Abstract

We demonstrate electron-stimulated migration for carbon monoxide (CO) molecules adsorbed on the Pd(110) surface, which is initiated by the excitation of a high-frequency (HF) vibrational mode (C–O stretching mode) with inelastic tunneling electrons from the tip of scanning tunneling microscopy. The hopping phenomenon, however, cannot be detected for CO/Cu(110), even though the hopping barrier is lower than in the CO/Pd(110) case. A theoretical model, which is based on the anharmonic coupling between low-frequency modes (the hindered-translational mode related to the lateral hopping) and the HF mode combined with electron-hole pair excitation, can explain why the hopping of CO is observed on Pd(110) but not on Cu(110).

  8. The STM images reported here were taken at 4.8 K with a commercial STM (Omicron LT) in ultrahigh vacuum. The Pd(110) and Cu(110) were cleaned with a standard procedure described previously. The molecules of CO are dosed on the surface through a dosing tube located near the sample surface.

  12. The dosing event was executed with fixed tunneling current (7 nA) and the dosing period (1 s) for all applied voltages. The hopping probability was defined as the number of events in which the change of the bonding site occurs out of the total number of dosing events. We do not know exactly when the hopping occurs in the dosing period of 1 s. Thus the remaining time after the event is a dead-time that makes the probability smaller. However since the probability per event was chosen to be <0.1 the error is <5% of the value shown in the figure.

  15. Again the error bar of 5% should be considered as due to the dead-time effect.
