Abstract
By reversing the polarity of extraction voltage for a liquid metal ion source, we measured I-V characteristics and observed emission patterns of field-emitted electrons. The Fowler-Nordheim plot of emissions from cleaned liquid surface did not fit a straight line. Emission patterns showed stable protrusions formed on the emitter tip. In order to study application feasibility of this electron source, further experiment was made by measuring the angular current density dI/dΩ and detecting SEM images.
