After bombardment, the target surfaCe is examined with SEM, and the surface composition of different topographical feature areas is measured with electron probe micrthanalyser (EPMA). The experiment results show that Cu atoms are preferentially ejected compared with Ni atoms, and Sn atoms come third within the ejection angle range from 0° to 60°. The results are discussed from the viewpoint of sputtering from a very rough surface.展开更多
