Abstract

Photographs of complex space charge configurations formed during nonequilibrium phase transitions in a gaseous conductor are presented. These appear when an external constraint induces a local gradient of electron kinetic energy, so that the regions where the excitation and ionization cross-section functions suddenly increase are spatially separated. Their genesis involves all key processes of a self-organized complexity.
