| Abstract: | The impurity effects on chemisorption for different binding s-ites(atop, bridge and centered)are investigated using the Green＇s function method and the LCAO Scheme. For each binding case, the change in density of states △P. and the chemisorption energy △w are calculated as functions of energies and the impurity parameters (△ε). Comparison between the three binding cases is made, and a qualitative understanding of the impurity effects on the chemiso-rPtion for the different binding sites is obtained. |
