Summary: The present study demonstrates the fabrication of an ITO/MnO2/ITO capacitor-based transparent ReRAM device. This device exhibits high transparency and stable bipolar resistive switching characteristics. It is found that the current in the low resistance state is governed by Ohmic conduction, while the high resistance state is dominated by trap-controlled space charge limited conduction mechanism. The resistive switching phenomenon in this device is attributed to the formation and rupture of conduction filament via electron trapping and de-trapping in oxygen vacancies. Reliability tests show good endurance and long retention for the MnO2-based device, making it a promising transparent electronic device for AI applications.

Summary: The resistive switching behavior of CsPbBr3 layer with different electrode materials and TiO2 layer conditions was studied in this paper. It was found that the Ni electrode had a larger ON/OFF ratio, and the TiO2 layer had little influence on the RS behavior. RS provides an effective method for defect control, and the influence on the photovoltaic effect was investigated.

Summary: This article presents a Cu/MoS2/NiMnIn memory structure for flexible electronics, and investigates the resistive switching characteristics. Two different devices were fabricated, one without sulfur vacancies and one with sulfur vacancies in the MoS2 thin film. The memory structure showed stable resistive switching behavior, good endurance cycles and data retention capability. Furthermore, the external temperature and magnetic field were found to affect the SET voltage and enhance the data storage capability of the device.

Summary: This article investigates the resistive switching mechanism in solid solution oxides, successfully fabricating binary and ternary solid solution films with switchable polarization, weak magnetism, and reversible resistive switching effects. Multi-stage resistive switching behavior was observed, with the binary film demonstrating four resistive switching states. The dominant role of oxide vacancy/valance exchange-induced defects in the resistive switching effect of complex oxide thin films is discussed.

Summary: By investigating the influence of different top electrode materials on resistive switching behaviors, it was found that the Al/citrus/ITO device exhibited more stable performance and higher ON/OFF ratio due to the fast formation of an aluminum oxide layer. The redox reaction between the aluminum electrode and citrus film played a significant role in the resistive switching properties of these structures.

Summary: In this paper, the resistive switching characteristics of HfO2-based metal-insulator-metal structures with four different metal bottom electrode materials (Au, Al, Pt, and Cu) are systematically investigated. It is found that Au and Pt have lower set and reset voltages, while Pt has a higher resistance ratio (R-off/R-on) of about 10(5). On the other hand, Al and Cu exhibit multilevel switching during the reset process. The oxygen affinity of the bottom electrode is expected to result in the formation of an interfacial layer with the active (HfO2) layer. Furthermore, the conduction mechanisms in the high resistance state (HRS) curves of these devices are studied, and the dominance of the Poole-Frenkel effect at higher voltages (> 1 V) in the HRS curve is observed.

Summary: This study investigates the resistive switching behavior of multilayered ReRAM devices by exploring the bilayer microstructure and top electrode configurations. It is found that the top electrode configuration has a significant impact on the switching types, while the bilayer microstructure has a relatively minor influence. Furthermore, modifying the top electrode configuration can greatly improve the switching ratio and reset voltage of the devices.
