摘要：
The surface of copper cathode foils with thicknesses up to 50 μm has been studied after a single discharge current pulse with an amplitude of up to 60 A and a pulse duration within 50–1300 μs 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.
