摘要：

The effect of adsorbate-induced surface reconstruction on the apparent pre-exponential factor and activation energy for desorption is analyzed and discussed. The reconstruction is assumed to be a continuous displacive phase transition caused by a Fermi surface instability. The adsorbate-induced changes in the surface are shown to result in a rather strong (of the order of 102) coverage dependence of the pre-exponential factor for desorption. The direction of the variation is in accordance with the compensation effect (the pre-exponential factor and activation energy decrease with increasing coverage. © 1990.
