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

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

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
