Abstract
We fabricated Spindt-type field emitters with four kinds of cathode materia l (Au, Ni, Pt, and Mo) and estimated the emission characteristics. The Pt e mitter showed the best emission characteristics with the lowest operating v oltage and the most stable emission among the four kinds of emitters. The d ifference of the operating voltage among the cathode material is attributed to the emitter shape. The reason the Pt emitter showed stable emission is its inert surface. Pt is a promising material for Spindt-type field emitter s from the cone shape, melting point, and inert surface. (C) 1999 Elsevier Science B.V. All rights reserved.
