<p>Microscale cold cathodes comprising a metallic emitter tip (21) with a very sharp end are manufactured by a method comprising forming a cone (20) of metal on a substrate (1) [Fig. 1C], oxidizing the surface of the cone [Fig. 1D], and removing the oxidized film (3) from the cone surface to produce an emitter tip [Fig. 1F]. <IMAGE></p> |
