Switching Characteristics

A kind of devices Pt/Ag/ZnO:Li/Pt/Ti with high resistive switching behaviors were prepared on a SiO2/Si substrate by using magnetron sputtering method and mask technology, composed of a bottom electrode (BE) of Pt/Ti, a resistive switching layer of ZnO:Li thin film and a top electrode (TE) of Pt/Ag. To determine the crystal lattice structure and the Li-doped concentration in the resulted ZnO thin films, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) tests were carried out. Resistive switching behaviors of the devices with different thicknesses of Li-doped ZnO thin films were studied at different set and reset voltages based on analog and digital resistive switching characteristics. At room temperature, the fabricated devices represent stable bipolar resistive switching behaviors with a low set voltage, a high switching current ratio and a long retention up to 104 s. In addition, the device can sustain an excellent endurance more than 103 cycles at an applied pulse voltage. The mechanism on how the thicknesses of the Li-doped ZnO thin films affect the resistive switching behaviors was investigated by installing conduction mechanism models. This study provides a new strategy for fabricating the resistive random access memory (ReRAM) device used in practice.

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.
