The stochastic equations of motion of the incident inert gas atom and the surface atom are treated under the Markov limit. The sticking probabilities are esti— mated from the micro-canonical sticking probabilities which are obtained by the numerical integration of the stochastic equations of motion. The adsorption energy for the isolate adsorption of Ar atom on copper surface is estimated to be about 750K on the basis of the observed sticking probability. By adding an Ar-Ar interaction potential, the sticking probability at the neighboring sites of an isolate adosorbed atom is estimated about 0.2. However, the obtained value is too small to explain the ob­served coverage dependence of the sticking probability of Ar on copper. The surface diffusion is de­duced to be necessary in order to reproduce the enhancement of the sticking probability near the iso­late adsorbed inert gas atom from some remarks obtained from the one dimensional model. departmental bulletin paper 福岡工業大学 2005-02-15 VoR application/pdf 福岡工業大学研究論集 2 37 185 190 RESEARCH BULLETIN OF FUKUOKA INSTITUTE OF TECHNOLOGY 02876620 https://fit.repo.nii.ac.jp/record/607/files/37(2)-185.pdf http://hdl.handle.net/11478/00001574 https://fit.repo.nii.ac.jp/records/607 jpn
