Thermal desorption of strained monoatomic Ag and Au layers from Ru(001)
- 1. Fritz-Haber-Institut der Max-Planck-Gesellschaft, Faradayweg 4-6, D-1000 Berlin 33, West Germany
Description
Model-independent or complete analysis of thermal desorption spectra suggests, in agreement with low-energy electron diffraction, that attractive lateral interactions between Ag atoms on a Ru(001) substrate lead to island formation for Ag coverages above 0.15 ML, with zeroth-order desorption kinetics and coverage-independent activation energy of desorption E, and preexponential factor ν. For the system Au/Ru(001), on the other hand, E and ν decrease monotonically with coverage, indicating that Au--Au interactions on Ru(001) are repulsive. For Θ/sub Ag/<0.15 and Θ/sub Au/<1 the systems exhibit a clear compensation effect between E and ν
