- Abstract
The characteristics of an overstressed nanosecond discharge between the copper electrode and the zinc electrode in argon are presented. In the process of microexplosions of inhomogeneities on the working surfaces of metal electrodes in a strong electric field, copper and zinc vapours are introduced into the discharge gap due to the formation of ectons. This can lead to the synthesis of thin films based on the zinc and copper nanoparticles and the zinc–copper bimetallic nanoparticles under conditions of irradiation of the substrate with the film during its synthesis by UV radiation from the discharge plasma in the copper and zinc vapours. Based on the solution of the Boltzmann kinetic equation for the electron energy distribution function (EEDF) with using the method of numerical simulation of the parameters of the discharge plasma in a gas–vapour mixture based on zinc, copper and argon, the plasma parameters (temperature Te and density Ne of electrons, discharge power losses per basic electronic processes and rate constants of electronic reactions) are calculated depending on the ratio E/N (where E is the electric field strength, N is the total concentration of discharge particles) and variations of the partial pressure of argon and the zinc and copper vapour.
