我们制作了四种阴极材料（Au，Ni，Pt和Mo）的Spindt型场发射体，并估计了发射特性。在四种发射体中，Pt发射体的发射特性最好，工作电压最低，发射最稳定。阴极材料之间的工作电压的差异归因于发射极形状。Pt发射体显示稳定发射的原因是其惰性表面。Pt是一种很有前途的Spindt型场致发射材料，因为它具有圆锥形状、熔点和惰性表面。
We fabricated Spindt-type field emitters with four kinds of cathode material (Au, Ni, Pt, and Mo) and estimated the emission characteristics. The Pt emitter showed the best emission characteristics with the lowest operating voltage and the most stable emission among the four kinds of emitters. The difference 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 emitters from the cone shape, melting point, and inert surface.
