Silver and Copper Alloys for the Top Electrodes of Memristive Structures Based on Poly- n -Xylylene

Comparative characteristics of M/PPX/ITO memristors based on poly- n -xylylene (PPX) with a bottom electrode made of a conductive layer of indium–tin oxide (ITO) and a top active electrode made of copper, silver or their alloy of various compositions ( M = Cu, Ag or Ag–Cu). The research results demonstrate that the most stable memristive characteristics are possessed by structures with top electrodes of pure metals.
