| Abstract: | Microscopic models to describe adsorbate dynamics induced by STM, e.g. the dynamics of STM-induced desorption of CO from Cu(111) and the dynamics of STM-induced rotation of acetylene on Cu(100) are presented. In these models, the relation between the change of the electronic state caused by an electron tunneling from an STM tip and the transition of the vibrational state for the molecular/intramolecular motion is taken into account from a microscopic point of view. Calculated probabilities for inducing desorption and rotation in these models agree with recent experimental results. |
