| Abstract: | The adsorptions of nitrogen atoms on Ru(0001), (1010) low index surfaces and (1120), (1121) stepped surfaces were investigated by the five-parameter Morse potential(5-MP) method in details. Calculated results demonstrate that N atoms show a tendency to be adsorbed at threefold sites. No subsurface state was found for N atoms on Ru(1010) surface. There exist 6 stable adsorption sites for N atoms on Ru(1121) stepped surface which can be classified into 3 types: the on-surface adsorption state, the facet adsor... |
