  • Graphene/Graphite-Based Filament for Thermal Ionization
    Publication number: 20180240637
    Abstract: Methods and systems for thermal ionization of a sample and formation of an ion beam are described. The systems incorporate a thermal ionization filament that is formed of a graphene-based material such as graphite, graphene, graphene oxide, reduced graphene oxide or combinations thereof. The filament material can be doped or chemically modified to control and tune the work function of the filament and improve ionization efficiency of a system incorporating the filament. The systems can be utilized in forming an ion beam for target bombardment or analysis via, e.g., mass spectrometry.
    Type: Application
