Abstract: The surface of copper cathode foils with thicknesses up to 50 $\mu$m has been studied after a single discharge current pulse with an amplitude of up to 60 A and a pulse duration within 50–1300 $\mu$s in air at atmospheric pressure. It is established that the foil surface upon discharge is covered by copper nanoparticles with diameters above 30 nm, which form an ordered array with a cellular structure and dimensions of up to several hundred nanometers. A possible mechanism of this self-ordered structure formation is qualitatively described.
