description: The purpose of the work is to create prototypes of low-voltage emitters with a narrow energy spectrum for high-resolution characteristic loss spectroscopy systems. As a result of the work, the current-voltage characteristics of a low-voltage field emission cathode consisting of a modified carbon layer of porous silicon were obtained and considered, the value of the threshold pulling field strength and the effective work function for this material were determined. The material has not been used in other scientific studies to date. Such low values of the electron work function and the pulling field voltage were obtained that had never before been achieved in the world using similar materials. Models of the behavior of the spectra of emitted electrons were obtained and analyzed. The hysteresis of the current-voltage characteristic was obtained and analyzed. During the work, the author presented intermediate results at two scientific conferences, one of which with international participation.
