The evolution of resistive switching behaviors dependent on interface transition layers in Cu/Al/FTO nanostructure

Publication date: 25 June 2020Source: Journal of Alloys and Compounds, Volume 827Author(s): Dai-Wen Tao, Zi-Jin Jiang, Jian-Biao Chen, Xiao-Gang Wang, Yan Li, Cheng-Wei WangAbstractHere, the Cu/Al/FTO layered nanostructure was designed and manufactured for investigating the roles of the interface transition layers in its resistive switching (RS) behaviors. The presence of the interface transition layers was confirmed by X-ray photoelectron spectroscopy (XPS) depth profile scans, indeed there is a very thin Al2O3 interface transition layer (interface 1, denoted as I1) produced by the natural oxidation within the Cu/Al interfaces, and a thicker interface transition layer (interface 2, denoted as I2, consisting of Al, Al2O3, SnO and SnO2) generated by interdiffusion and redox reaction between the Al/FTO interfaces. The test results showed that the device, with actual structure of Cu/I1/Al/I2/FTO, could show the evolution of resistive switching behaviors: from irreversible write-once-read-many-times (WORM) characteristics to reversible bipolar resistive switching (BRS) behaviors with negative differential resistance (NDR) effect and subsequent disappearance and recovery of the BRS. Correlation analysis suggests the observed RS behaviors strongly depend on the permanent rupture of pre-existing Al conductive filaments (Al-CFs) in the transition layer I2, and their evolution. This work gives an insight into the role of interface transition layers in RS behaviors and provides a simpl...

Abstract The purpose of this study was to evaluate the quality of surface contouring of chondromalacic cartilage by bipolar radio frequency energy using different treatment patterns in an animal model, as well as examining the impact of the treatment onto chondrocyte viability by two different methods. Our experiments were conducted on 36 fresh osteochondral sections from the tibia plateau of slaughtered 6-month-old pigs, where the thickness of the cartilage is similar to that of human wrist cartilage. An area of 1 cm2 was first treated with emery paper to simulate the chondromalacic cartilage. Then, the tr...

CONCLUSIONS: We were able to achieve a high accuracy for machine learning technique in distinguishing BD from HV using a combination of multimodal neuroimaging and neurocognitive measures. Findings of this proof of concept study, if replicated in larger samples, could have potential clinical applications. PMID: 32143176 [PubMed - as supplied by publisher]

AbstractIntroductionDespite technical progress, ventricular tachycardia (VT) recurrence after unipolar ablation remains relatively high (12% ‐47%). Bipolar ablation has been proposed as an appealing solution that may overcome limitations associated with unipolar ablation settings. We designed an animal study to compare bipolar (BPA) vs sequential unipolar ablation (UPA) using contact force‐sensing technology on both ablation catheter s.MethodsTwenty large white female pigs (6 ‐months‐old, 50–60 kg) underwent multiple RF ablations (30 W, 60 seconds, 30 mL/min irrigation) on the vent...

AbstractMassa intermedia (MI) is an inconsistent midline structure in the human brain that is absent in approximately 30% of the population. Absence of MI is seen more frequently in schizophrenia spectrum disorder and bipolar disorder. However, very little is known about the normal role of MI in the human brain. The purpose of this study was to investigate the role of human MI in cortical and subcortical cognitive processing as determined by differences between subjects with and without MI. Using the Human Connectome Project database, a cohort of randomly selected participants were selected to (1) identify presence, absenc...

CONCLUSIONS.: Despite sharing a lower IQ and a higher prevalence of psychiatric disorders, brain abnormalities in BDo appear less pronounced (but are not absent) than in SZo. Lower ICV in SZo implies that familial risk for schizophrenia has a stronger association with stunted early brain development than familial risk for bipolar disorder.
