Thermal Desorption of Xe from the (110) Plane of Tungsten.
Abstract
Thermal Desorption of Xe from the (110) plane of tungsten can be followed layer by layer for 3 monolayers. In each case desorption is zero order until coverage is 0.3, when a sharp switch to first order occurs. The presence of even small amounts of oxygen kills the zero order regime in the first layer. Possible explanations for this behavior are given. The activation energies of desorption are shown to less than the corresponding enthalpies in each case, and the meaning of this result is discussed.
