Unipolar Resistive Switching Behavior Study in CuxO Thin Films at Different Annealing Temperatures

Abstract

We investigated unipolar resistance switching in CuxO thin films. We studied on the resistive switching behavior associated with the annealing temperature of CuxO thin films and focused on HRTEM, XPS and AFM analyses. In this paper we investigated the surface and interface structures of CuxO films. Results show that there is a mount of oxygen content in the CuxO thin films which is contained in Cu (Ⅱ) oxides and Cu (Ⅰ) oxides. When annealing temperature increases the qualification of oxygen vacancies increase and more oxygen vacancies is connected with top and bottom electrode.
