Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

<p>The oxygen concentration profiles, which develop at the interfaces between niobium pentoxide and the Al or Pt electrode in a metal-insulator-metal stack, were investigated by means of the X-ray and electron energy loss spectroscopies in a scanning transmission electron microscope with high resolution. The contact between Al and Nb<sub>2</sub>O<sub>5</sub> was found to facilitate diffusion of oxygen from Nb<sub>2</sub>O<sub>5</sub> to the Al electrode and to support the formation of a thin aluminum oxide layer at the Nb<sub>2</sub>O<sub>5</sub>/Al interface. In contrast, almost no diffusion of oxygen from Nb<sub>2</sub>O<sub>5</sub> was observed at the Nb<sub>2</sub>O<sub>5</sub>/Pt interface. Different extent of the oxygen diffusion correlates with the observed differences in the resistive switching of the Pt/Nb<sub>2</sub>O<sub>5</sub>/Al and Pt/Nb<sub>2</sub>O<sub>5</sub>/Pt stacks.</p>
