Title
The influence of the surface binding energy on the emission of $MCs^{+}$ secondary ions from elemental targets in secondary ion mass spectrometry
Author
Abstract
 Energy distributions of MCs(+) ions, emitted from several elemental (Zn, Ge, Cu, Ni, Mo) targets using Cs+ ion bombardment, were measured. A comparison with the theoretical energy distribution of sputtered neutral atoms M reveals that the MCs(+) distribution and the M distribution depend in the same way on the elements' surface binding energy U-0, Increasing U-0 leads to a broader distribution, characterized by higher mean emission energy. Furthermore, the MCs(+) mass signal increases with a decrease in mean emission energy. This provides evidence for the correlated emission of the two partners forming the MCs(+) molecule.
