摘要：

Field electron emission patterns from a [011]-oriented tungsten tip coated with liquid lithium film were observed. For the film thickness between 5 and 30 nm, emission patterns showed the formation of liquid lithium cones on the facets of the tungsten surface. The Fowler-Nordheim plots showed the presence of the space charge effect. The increase of the number of liquid cones with tip voltage was qualitatively explained in terms of the space charge effect. For the film thickness more than 30 nm, only pulsed explosive emission was observed.
