Research Abstract

The mechanism of voltage-induced resistance switching observed in transition metal oxides has been studied. To evaluate changes in the chemical state of the switching material, we fabricated a transition metal nanowire device, which enables us to probe the chemical state using various surface analysis methods. 3D nano-ESCA experiments revealed that the redox reactions of transition metal-e.g., the oxidation of Ni to NiO and the re-reduction to Ni-give rise to the reversible alternation of the resistance state.The resistance switching device may therefore be considered as an electrochemical phase change memory.
