Abstract

Cathode-directed sparks engrave in a specially prepared, originally low-conducting nonlinear silver-based material beyond a critical electric power input highly structured discharge patterns which exhibit an anomalous potential distribution consisting of an electrical double layer in series with a region of high electrical conductivity.
