用Fowler-Nordheim场致发射方法计算了氢化氮化碳（a-CNx：H）非晶相的功函数。先在导电ZnO：Al晶须上沉积金属膜以确定场发射体尖端处的几何场增强因子。测量了金属薄膜沉积后晶须尖端的曲率半径。下一个利用金属的功函数和发射极尖端的曲率半径计算了陶瓷晶须的几何场增强因子。最后，利用具有几何场增强因子的Fowler-Nordheim方程，导出了a-CNx：H的功函数。a-CNx：H的功函数取决于官能团。
The work function of the amorphous phase of hydrogenated carbon nitride (a-CNx:H) was calculated Using Fowler-Nordheim field emission. First. metal films ere deposited on conductive ZnO:Al whiskers to determine the geometric field enhancement factor at the tip of the field emitter. The radius of Curvature at the whisker tip after tile deposition of metal films was measured. Next. the geometric field enhancement factor of ceramic whiskers was calculated using the work function of the metals and the radius Of curvature of the emitter tip. Finally, the work function of a-CNx:H was introduced using the Fowler-Nordheim equation with the geometric field enhancement factor. The work function of a-CNx:H is dependent upon the functional group.
