- Sticking_probability abstract "The sticking probability is the probability that molecules are trapped on surfaces and adsorb chemically. From Langmuir's adsorption isotherm, molecules cannot adsorb on surfaces when the adsorption sites are already occupied by other molecules, so the sticking probability can be expressed as follows:s=s0(1-c)where s0 is the initial sticking probability and c is the coverage.Similarly, when molecules adsorb on surfaces dissociatively, the sticking probability iss=s0(1-c)2Although these equations are simple and can be easily understood, they cannot explain experimental results. Their simple explanation is not enough.In 1958, P. Kisliuk presented an equation that can explain experimental results. In his theory, molecules are trapped in precursor states (physisorption) before chemisorption. Then the molecules meet adsorption sites that molecules can adsorb to chemically, so the molecules behave as follows.If these sites are not occupied, molecules desorb from the surface (pd: probability) move to the next precursor state (pm: probability) adsorb on the surface chemically (pa: probability)and if these sites are occupied, they desorb from the surface (pd': probability) move to the next precursor state (pm': probability)Then the sticking probability iss=s0(1+cK/(pa+pd)-1(K=pd'/(pa+pd))When K=1, this equation equals Langmuir's adsorption isotherm.".
