Abstract
Double barrier memristive devices are under investigation, which consist of a 2.5 nm thick NbOx (or HfOx) layersandwiched between an Al2O3 tunnel barrier and a Schottky-like contact to an Au top electrode. These devices showbipolar interface-based analogue resistive switching which is most probably due to the migration of oxygen vacanciesthat change the interfacial properties [1]. Inside the tunnel barrier, argon and oxygen gas was found in pores of FIBlamellas which are vacuum-tightly encapsulated in the thin film. The formation and the influence of these pores on thedevices are analyzed in this study.
