we report reproducible resistive switching performance and relevant physical mechanism of Pt/La0.7Sr0.3MnO3/Nb0.05Bi0.95FeO3/Nb:SrTiO3 ferroelectric heterostructure which was fabricated by pulsed laser deposition. This device exhibits a nonvolatile resistive switching with a resistance ratio of up to 60 under 2V/-3V pulse voltages at room temperature. Low voltage readout, reliable resistance switching reproducibility and good time retention, indicating promise for non-destructive readout nonvolatile memories. In this metal/p-semiconductor/ferroelectric/n-semiconductor heterostructure, the mechanism of resistive switching behavior would be attributed to the ferroelectric polarization enhanced field-induced charge redistribution at the semiconductor/ferroelectric interface, resulting in the modulation of the interface barrier height. Keywords: Resistive switching, Ferroelectric resistive switching, Ferroelectric field effect.

Switching Characteristics

In this study, we have investigated influences of the thickness on the structure, surface morphology and resistive switching characteristics of CrOx thin films prepared by using DC reactive sputtering technique. The Raman and FTIR analysis revealed that multiphases including Cr2O3, CrO2, Cr8O21... phases coexist in the microstructure of CrOx film. It is noticed that the amount of stoichiometric Cr2O3 phase increased significantly as well as the surface morphology were more visible with less voids and more densed particles with larger thickness films. The Ag/CrOx/FTO devices exhibited bipolar resistive switching behavior and high reliability. The resistive switching ratio has decreased slightly with the thickness increments and was best achieved at CrOx – 100 nm devices.
