Interfacial chemical bonding-mediated ionic resistive switching.

In this paper, we present a unique resistive switching (RS) mechanism study of Pt/TiO/Pt cell, one of the most widely studied RS system, by focusing on the role of interfacial bonding at the active TiO-Pt interface, as opposed to a physico-chemical change within the RS film. This study was enabled by the use of a non-conventional scanning probe-based setup. The nanoscale cell is formed by bringing a Pt/TiO-coated atomic force microscope tip into contact with a flat substrate coated with Pt.
