基于Richardson-Dushman方程提出了阴极材料的品质因数。通过计算硼化物、碳化物、氮化物、氧化物和难熔金属的性能优值，比较了这些高亮度阴极材料的性能特点。过渡金属碳化物有望成为高亮度电子源。
A figure of merits of cathode material based on the Richardson-Dushman equation is proposed. Calculating the figure of merits of borides, carbides, nitrides, oxides and refractory metals, the characteristic features of these materials for the high brightness cathode are compared with each other. It is inferred that the carbides of transition metals are promising for a high brightness electron source.
