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.

Lithium (0, 1.0 and 10 at.%)-doped ZnO (LiZnO) polycrystalline thin films were deposited on Pt/SiO2, LaB6/Al2O3, Au/SiO2 and 20 at.% fluorine-doped SnO2(FTO)/glass substrates by an e-beam evaporation method. Metal/LiZnO/Metal sandwich structures were constructed by depositing different top electrodes (Ag, Al and Au) to find memristive characteristics depending on the lithium content and electrode materials. Compared with undoped and 1%Li-doped ZnO devices, the 10 at.%Li-doped ZnO (10LiZnO) device exhibits resistive switching memory. The Ag/10LiZnO/Pt and Ag/10LiZnO/LaB6 memory devices exhibit unipolar resistive switching behavior while bipolar resistive switching in Ag/10LiZnO/FTO, Au/10LiZnO/FTO and Al/10LiZnO/LaB6 structures is revealed. The dominant conduction mechanisms are explained in terms of Ohmic behavior, space charge limited current (SCLC) and Schottky emission for the URS and BRS behaviors.

To effectively improve the uniformity of switching behavior in resistive switching devices, this study developed magnesium zirconia nickel (MZN) nanorods grown on ITO electrodes through hydrothermal method. The field emission scanning electron microscope image shows the NR formation. Al/MZN NR/ITO structure exhibits forming-free and bipolar resistive switching behaviors. MZN NRs have relatively higher ON/OFF ratio and better uniformity compared with MZN thin film. The superior properties of MZN NRs can be attributed to its distinct geometry, which leads to the formation of straight and extensible conducting filaments along the direction of MZN NR. The results suggest the possibility of developing sol–gel NR-based resistive memory devices.
