The degradation mechanism of field emission cathodes based on carbon nanotubes was investigated in the presented work. Emission current instability came from the adsorption/desorption processes on the cathode surface. During the long-time tests, peri

The significant current degradation of the carbon nanotubes cathode was found in the presented work. This current instability came from the adsorption desorption processes on the cathode surface. During the long-time tests the periodical changing of

At this report, the producing technology of the field emission cathode based on ball-milled carbon fibers is represented. The method of the carbon fiber powder with the optimal particle size obtained is described. For the deposition on the cathode ba

By using the method of pulsed field electron emission, it is shown that, as the current density approaches the ultimate value, there appears a bright ring around a normal field-emission image. This effect is frequently observed in the case of planar

In the present work, we studied the influence of the distance between electrodes in the electrophoretic process of flat cold cathode fabrication on the uniformity of the emission centers distribution. As the emitting material, we used single-wall car

The training method for planar cathode based on carbon fiber powder significantly improves the field emission performances. The main point of the training is the forming the optimized emission surface under the residual gases ion bombardment during c

In this paper, we discuss the method of FEC comparison. Such method should satisfy the following requirements: possibility to investigate big amount of cathode per short time and possibility to investigate cathode inside a finished device. Moreover t

A technique for reducing the work function of a field-emission graphite cathode by doping it by an alkaline-earth metal (barium) is suggested. A model of formation of a barium monolayer on the cathode surface is proposed. Field-emission tests show th

Here we report about the effect of ring appearance in the flat cathode structures. During the tests of flat cathodes produced by electrophoresis, electrochemical deposition or by CVD methods we observed the appearance of one, two and sometimes three

The electron gun with field emission cathode is developed. The cathode was made of a bundle of carbon fibers. Specific properties of electron gun with bundles of carbon fibers are related to mechanical displacement of carbon fibers in the bundle. Spe
