Abstract

We have studied the change of Li⁺and F ^-secondary ion intensities with the matrix transition from submonolayer LiF on gold to thick LiF by time-of-flight secondary ion mass spectrometry. Based on direct recoil particle measurements and Monte Carlo simulations, we estimated that the ratio of Li⁺/F ^-secondary ion yields did not change significantly with the matrix. From the results, it is suggested that the bond breaking model can be applied for submonolayer LiF on gold as well as for thick LiF.
