摘要
The instability of field emission current arises from the atomic charges of the field emitter surface which can be induced by the sputtering of the secondary ions, by surface diffusion of contaminant atoms, and by the dynamical behavior of the emitter surface itself. Various possible causes of the instability and a few possible remedies for alleviating these problems are discussed.
