Electroforming of NbOx memristors produces correlated micrometer-scale oxygen enrichment and Pt-rich filaments via Joule heating and thermal cycling, contrary to expectations of inert Pt electrodes.
The finite element simulations employed the electric currents and heat transfer modules in COMSOL to simultaneously solve the coupled electrical and thermal transport equations

Anomalous Platinum and Oxygen Transport during Electroforming of NbOx Memristors
Electroforming of NbOx memristors produces correlated micrometer-scale oxygen enrichment and Pt-rich filaments via Joule heating and thermal cycling, contrary to expectations of inert Pt electrodes.
