A low-cost high-performance solid-state flexible asymmetric supercapacitor (ASC) with α-MnO2 nanowires and amorphous Fe2O3 nanotubes grown on carbon fabric is first designed fabricated. The assembled novel ASC device an extended operating voltage window of 1.6 V exhibits excellent performance such as a high energy density 0.55 mWh/cm(3) good rate capability. devices can find numerous applications effective power sources, powering color-switchable sun glasses smart windows.
Few-to-monolayer germanium selenide, a new IV-VI group layered material recently fabricated by mechanical exfoliation and subsequent laser thinning, is promising in very fast broadband optoelectronic applications for its excellent stability, complicated band structures, inert surface properties, being natural p-type semiconductor. However, large-scale production of such few-layer GeSe devices with superior performance still early stages. In this study, field-effect transistors made direct...
<title>Abstract</title> Using spin-orbit torque (SOT) to manipulate magnons has played a crucial role in magnon spintronics. However the effect of on SOT remains elusive within context electron Here, we report observation magnon-induced an epitaxial Co film through precise low-magnetic-field measurements second harmonic voltages both longitudinal and transverse directions. Unlike conventional field-like SOT, which operates independently magnetic field, magnonic exclusively emerges at low...
Quantum dots (QDs) are promising color conversion materials for efficient full-color micro light-emitting diode (micro-LED) displays owing to their high purity and wide gamut. However, achieving high-resolution QD patterns with enough thickness is challenging. Here, we demonstrate a facile compatible approach by combining replicate molding, plasma etching transfer printing produce sufficient over ten micrometers in range of resolutions. Our technique can remarkably simplify the preparation...
Enhancement of spin-orbit torque (SOT) efficiency in ferromagnet/heavy-metal bilayer is promising for the realization low-power spintronic devices. Here we show that inserting a single-layer ${\mathrm{WS}}_{2}$ between substrate and Co/Pt layers, can reduce Co coercivity by $\ensuremath{\sim}28%$ increase dampinglike SOT $\ensuremath{\sim}30%$, up to 35.07 Oe/$({10}^{7}\mathrm{A}\text{/}{\mathrm{cm}}^{2})$. When with different further demonstrate these phenomena only exist odd i.e.,...
Unidirectional magnetoresistance (UMR) has garnered extensive attention for its rich physics and potential applications. The prevailing belief is that indispensable ferromagnetic films serve as scattering sources of polarized electrons or noncentrosymmetric systems cause spin band splitting, driving most research toward ferromagnet/normal-metal bilayer nonmagnetic Rashba systems. However, our observations reveal a significant UMR in consisting solely the oxidized light metal...
The hyperfine magnetic field (HMF) distributions obtained from the M\"ossbauer spectra of alloys ${\mathrm{Fe}}_{\mathit{x}}$${\mathrm{Cu}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$ prepared by ball milling are studied. HMF samples milled for 160 h decrease 30 to 24 T when Fe proportion x decreases 0.8 0.6 and 0.5, while, x=0.6 as time t changes 10 40 h, high fields in distribution gradually, middle increases. These results agree with x-ray diffraction extended x-ray-absorption fine structure...
Abstract Hybrid structures of quantum dots (QDs) on two-dimensional materials have aroused great interest because their high absorbance properties and tunable wavelength detection ranges. In this work, 1.44 times the photoresponse bandwidth PbSe QDs atomic-layered GeS hybrid structure devices is achieved compared with pure due to transfer photogenerated carriers between film. A doubling peak photoresponsivity obtained at a 635 nm, detectivity increases by 39.5 27.4 under 808 980 nm...
Increasing the efficiency of spin–orbit torque (SOT) is great interest in applications for magnetic random access memory and logic devices due to decreased energy consumption. Here, we present that SOT Pt/Co/Ta films with perpendicular anisotropy can be improved by swift high-energy heavy Fe11+ ion irradiation, which an effective method alter crystallinity, interface roughness, defects ferromagnet/heavy metal heterostructures. Specifically, show optimal at fluence around 1.0 × 1013 ions/cm2...
Abstract An unexpectedly larger current-induced spin–orbit torque in oxidized Cu (CuO x )/ferromagnet (FM) than heavy-metal/FM has recently attracted intense attention spintronic studies. Although the two mechanisms, interfacial Rashba Edelstein effect and spin-vorticity coupling, have been put forward based on different conductive features of CuO , i.e. electrical insulator gradient mobility, detailed investigation transport is still lacking. Here we experimentally report positive negative...
