Dynamic effects of promoters on associative desorption.
The kinetics of the associative desorption of A(2) in the presence of coadsorbed promoter species B is studied under conditions of nonequilibrium by the analysis of thermal desorption spectra obtained by Monte Carlo simulation. A rich variety of behaviors is found and discussed with regard to the interplay between the concentrations of promoter species, the surface mobility of A and B, and the interparticle interactions.
