Noise Diagnostic Method of Experimental Cold Field-Emission Cathodes
Original language description
Technological imperfections and impurities, which are caused mainly by experimental preparation of the composite cold field-emission cathodes, prove itself most likely as a source of superfluous current and redundant noise. The noise spectrum densities of the emission current along with the main sources of noise were characterized in previous paper. In this paper, it is dealt with the G-R component. It is supposed, that the generation-recombination noise results from the electron movement which takes place on the surface of the cathode. Presuming, that one part of electrons is being evaporated out of the cathode surface, the second part is being attracted and caught back on the surface. Considering these interactions between two reservoirs, a model ofadsorption-desorption noise can be formulated on the basis of the Kolmogorov equation.
