The reproducible forming-free resistive switching (RS) behavior in rare-earth-oxide Gd2O3 polycrystalline thin film was demonstrated. characteristic of this RS similar to that other forming-necessary binary materials except its initial resistance starts from not the high state (HRS) but low (LRS). An ultrahigh ratio HRS LRS about six seven orders magnitude achieved at a bias voltage 0.6 V. Mechanism analysis indicated existence metallic Gd films plays an important role performance. Our work...
Abstract As a remarkable gas‐sensing material, ZnO is limited by the gas selectivity of its indiscriminate response to multiple gases. Herein, abnormal p‐type responses ether but n‐type othervolatile organic compoundsare observed in Co‐ZnO nanocomposite films. It should be attributed inversion region at particle interface, on which tends selectively adsorb. By controlling Co content, nanoflower structure realized, significantly increases adsorption sites and enhances eight times that film....
Two-dimensional superconductors exhibit intriguing quantum physical phenomena and hold promising potential for superconducting circuit applications due to their inherently broken inversion symmetry, which can introduce additional degrees of freedom related spin or momentum. Achieving chemical stability in atomic layer 2D superconductors, including mechanical exfoliation film deposition, remains both fundamentally technologically challenging. Naturally, interfacial superconductivity, enclosed...
Abstract The transient photoconductivity process of silicon carbide photoconductive semiconductor (SiC PCSS) mainly depends on the optical excitation to generate electron-hole plasma in substrate. Among them, photon injection rate has a significant impact generation and transport photo-generated carriers within PCSS as an important parameter laser pulse. effect output characteristics vanadium-doped (V-doped) 4H-SiC under 532 nm non-intrinsic triggering is experimentally studied this article....
This article introduces a memristor-coupled oscillatory network utilizing niobium dioxide (NbO2) memristors and biomimetic spider web structure. It focuses on the dynamic behaviors of single oscillators small-scale networks within this unique system, particularly emphasizing voltage, current, frequency characteristics. By strategically applying step voltage signals 1 + 3 node single-layer bio-inspired network, disturbance or multiple disturbances were addressed under continuous external...
Abstract Neuristors show promise in replicating human-brain neuronal functions, yet their application to sensory neurons, especially for mimicking complex auditory behaviors like sound localization, remains challenging. This study uncovers an asymmetrical response the output signals of NbO2-based neuristor: positive current inputs induce periodic oscillations, while negative equal magnitude trigger bursting spikes. A dual-input system with interaural time differences is presented...
Recently, magnetic metal-semiconductor nanocomposite films with a uniform superparamagnetic structure have attracted increasing interest in negative magnetoresistance (MR) properties at room temperature (RT). In this work, we designed and prepared an original nonuniform coexistence of size-distributed ferromagnetic Co clusters particles Co–ZnO films, content between 41 65 at.%. The film 49 at.% shows large RT MR maximum value over 9.5%. As increasing, the grow both quantity size. Meanwhile,...
Despite more than ten years of extensive research, the superconducting mechanism iron-based superconductors (FeSCs) is still an open question. Generally, high-temperature superconductivity often observed with suppression magnetic ordering, spin-density-wave, or even structure transition by carrier doping. Furthermore, electronic state ordering also at temperatures close to above these transitions. Due its proximity and disappearance near optimal superconductivity, it has been suggested...
An optical microscopy study of ordered structures and self-organized phenomena in a continuous gold film system deposited on silicone oil surface is presented. Band-shaped patterns, namely bands, are formed after deposition under certain condition. The bands composed large number parallel key-shaped domains with different width but nearly uniform length. Further experiments show that the patterns result from compressive stress films. We also formation mechanism internal free sustained
Strong spin-orbit coupling and relatively weak hyperfine interactions make germanium hole spin qubits a promising candidate for semiconductor quantum processors. The two-dimensional gas structure of strained Ge wells serves as the primary material platform qubits.A low disorder environment is essential this process. In work, we fabricated Ge/SiGe heterojunction with 60 nm buried well layer on Si substrate using reduced pressure chemical vapor deposition technology. At temperature 16 mK, when...
