Abstract
We investigate the temperature dependence of the mass spectrum of the ion beam emitted by an Au77Ge14Si9 liquid metal alloy ion source. Our results strongly point towards the co-existance of two mechanisms for the emission of doubly-charged monomer ions: direct field evaporation and post-ionization.
Keywords: liquid metal alloy ion source; mass spectra; emission mechanism; field evaporation post-ionization
