“…The results of systematic studies of the characteristics of an overvoltage nanosecond discharge between electrodes made of copper, stainless steel, aluminum, and chalcopyrite (CuInSe2) in air, nitrogen, and argon are given in [1]. Such a discharge can be a point source of ultraviolet radiation, and from its plasma it is possible to deposit thin nanostructured films of oxides of transition metals and chalcopyrite [2]. The introduction of electrode material into the plasma in these experiments occurs in the process of microexplosions of natural inhomogeneities of the electrode surface in a strong electric field during the formation and decay of ectons [3].…”
