Abstract :
We have developed a new method for fitting the current-voltage (I-V) characteristics of the field emission arrays (FEAs) that may be operated at high current density. The self-consistent model is demonstrated to be a good fit to the I-V characteristics of high current density FEAs. This also indicates that the space charge effects play an essential role in the saturation behaviour of FEAs.
