Abstract: A two-terminal atom-based switching device having a fast operating speed and high durability and a manufacturing method thereof are disclosed. It is possible to reduce a forming voltage during positive voltage forming by forming an oxygen vacancy percolation path through negative voltage forming, which is first forming, and forming high binding energy and low formation energy between oxygen vacancies and metal ions implanted through positive voltage forming which is second forming after the negative voltage forming. Further, since a significant amount of metal ions implanted into the insulating layer through negative voltage application switching after the positive voltage forming is removed, the volatility of the two-terminal atom-based switching device may be improved, and a stuck-on failure phenomenon in the durability may be prevented.

Abstract: The present invention relates to a method of improving the corrosion resistance of a metal substrate surface using an oxygen reduction catalyst, which may improve the corrosion resistance of the metal substrate surface by coating the metal substrate surface with the oxygen reduction catalyst so that the metal substrate surface is changed to a passive state through the action of the oxygen reduction catalyst in an environment in which a stable oxide layer is not spontaneously formed on the metal substrate surface. The present invention has an advantage in that it can dramatically improve the corrosion resistance of the metal substrate under a corrosive environment by allowing a recoverable oxide layer to be formed on the metal substrate surface through the action of the oxygen reduction catalyst, applied to the surface, even in an environment in which an oxide layer is not spontaneously formed on the metal substrate.
