A tin liquid metal ion source (LMIS) containing ∼14% Pb has been studied. From a careful examination of the mass spectra of the source, it is concluded that post-ionisation (PI) is the most probable mechanism for the formation of Pb2+ ions. In the

The mass spectra of the beam emitted by a Au82Si18 eutectic molten metal ion source are investigated in detail as a function of emitter temperature. At the conclusion of the work it emerges that while Au+, Si+, and Si++ are the result of direct field

The energy distribution of the monomer ion species is studied as a function of emitter temperature for an Au 82 Si 18 eutectic liquid metal alloy ion source (LMAIS). Secondary peaks, or shoulders, in the distribution of some of the species are explai

Tin is an important metal with new potential applications regarding the fabrication of novel devices. In this work the mass spectrum of a tin liquid metal ion source (LMIS) is studied in detail. Sn++ was found to dominate in the beam both over Sn+ an

Focused silicon beams are useful for direct write applications, e.g., lithography on silicon without the undesirable effect of substrate contamination. However, since pure silicon is not amenable to liquid metal ion source (LMIS) manufacture, a suita

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-existence of two mechanisms for the emission of doubly-charged monomer i
