Test structures of memristive devices were prepared by tip-induced oxidation of thin titanium films using atomic force microscope. Electrical measurements of such Ti/TiOx/Ti devices confirmed their memristive behavior and inferred presence of diffusion processes in the TiOx barrier. Consequent Kelvin probe force microscopy studies provided evidence for the diffusion processes as well as for expected electricfield-induced ionic/charge redistribution in the oxide barrier. Time evolution of the surface potential due to the diffusion processes in the TiOx barrier revealed minute-scale (at least) retention times of the devices. The work presents a widely utilizable approach to search for novel oxide materials for perspective memristive applications as well as alternative technology for fabrication of memristive nanodevices in geometry favoring advantageous scanning probe microscopy studies of their in-barrier processes.
