Different from conventional unipolar-type 1D–1R RRAM devices, a bipolar-type memory device concept is proposed and successfully demonstrated by the integration of Ni/TiOx/Ti diode Pt/HfO2/Cu bipolar cell to suppress undesired sneak current in cross-point array. The not only achieves self-compliance resistive switching characteristics reverse bias diode, but also exhibits excellent such as uniform switching, satisfactory data retention, scalability, which give it high potentiality for...

The stabilization of the resistive switching characteristics is important to random access memory (RRAM) device development. In this paper, an alternative approach for improving in ZrO2-based devices has been investigated. Compared with Cu/ZrO2/Pt structure device, by embedding a thin TiOx layer between ZrO2 and Cu top electrode, Cu/TiOx–ZrO2/Pt exhibits much better characteristics. improvement might be attributed modulation barrier height at electrode/oxide interfaces.

Eosinophilic enteritis, one type of eosinophilic disorders, is a rare disease characterised by infiltration the small bowel with numerous mucosal eosinophils or/and ascites pathologically. The prevalence enteritis fewer than ten in100,000 people, frequently occurred in female1. pathogenesis poorly known, but allergic diseases, autoimmune connective reaction and intestinal dysbiosis have been implicated.

The RESET switching of bipolar Cu/HfO2/Pt resistance random access memory (RRAM) is investigated. With a statistical methodology, we systematically analyze the voltage (VRESET) and current (IRESET). VRESET shows U-shape distribution as function RON according to scatter plot raw experimental data. After data correction by series (RS), nearly constant, while IRESET decreases linearly with RCF. These behaviours are consistent thermal dissolution model RESET. Moreover, distributions strongly...

Scaling is a key issue for resistive switching (RS) memory before commercialization. In this letter, we reveal the impact of electrode diffusion on device performance as thickness RS material scaled. Serious deterioration on/off ratio and yield was observed when scaled below 3 nm. A new method two-step deposition accompanied with reoxidization process employed to overcome problem. Significant improvements such forming free, low RESET current (~1 μA), high (>; 100) 100% were achieved thereafter.

Single-fiber laser treatment of the prostate has been widely accepted in clinic due to its minimal invasiveness and high controllability. However, for large tumors, multiple insertions probe would be needed achieve full coverage tumor, increasing complexity occasionally resulting incomplete killing tumor cells a mismatch between planned insertion location actual location. Treatment with dual-fiber results greater lesion following single probe, being even than sum two sequential single-fiber...

In this paper, the effect of a low constant current stress (CCS) treatment on performance Cu/ZrO2/Pt resistive switching device is investigated. The conductance increases about two orders magnitude after CCS treatment, indicating that some defects are introduced into ZrO2 matrix and can be regarded as an electrical doping process. Benefiting from these defects, better obtained including forming voltage, reset current, uniform good endurance characteristics.
