| Abstract: | The 5-parameters Morse potential of interaction between hydrogen and ruthenium was constructed. The adsorption and diffusion of a hydrogen atom on Ru(0001) and Ru(1010) surfaces were studied by means of the classical pair-potential. Data of the adsorption sites, adsorption geometry, binding energy and eigenvibration energy etc. for a hydrogen atom on the above surfaces were obtained. They are in agreement with the experimental results well. Then the structures of potential energy surfaces for the above systems were systematically investigated. |
