Control of formation sites for liquid-Li cones on a W〈100〉 tip by means of the remolding method

For a liquid-Li coated W〈100〉 field emitter tip, control of the formation sites of field-stabilized Li cones was tried by applying the remolding method to the substrate W tip. Observation of the field emission patterns showed that the field-stabilized cones are reproductively formed on the remolded facets, namely (310), (411) and (111). This means that remolding is a useful method for control of the formation sites of the liquid-Li cones and the cones are formed on the facets on which strong electric fields exist
