✦ Synopsis
The observation of the motion of an adatom on the reconstructed Ge Ž . 111 is a rare event, which will be examined by way of simple adatom᎐surface interaction models. Estimations of the residence time of adatoms on energetically favorable sites indicate that a thermal excitation can account for casual adatom motion and that a strong tip᎐surface interaction is not obviously needed to explain the changes Ž . found in sequences of scanning tunneling microscopy STM images of the same surface areas.
