Analysis of simple and single thermal desorption spectra: application to hydrogen (deuterium) desorption from a thin gold film

An effective method of computing kinetic parameters (n,V,Ed) of thermal desorption from the experimental thermal desorption curve has been elaborated. So far the Downhill Simplex Method in Multidimensions for minimization and the Runge-Kutta method for solvation the Polanyi-Wigner equation, for any set of kinetic parameters proposed by the Simplex Method, have been applied. The fitting procedure is demonstrated on examples of low coverage thermal desorption spectra for H (D) adsorbed on a thin gold film surface at 78 K.
