We achieved fully-printed SnO 2 based n-type thin-film transistors with high electrical performance and robust mechanical flexibility, promising for constructing low-cost, high-performance flexible electronic devices circuits.
In this study, to explore the impact of nitrogen on chemical composition, morphology, microstructure, as well intrinsic stress titanium films, nitrogen-doped thin films prepared by direct current reactive magnetron sputtering, with different ratio doping into Argon gas, have been characterized. After check grazing incidence X-ray reflectometry (GIXR), thickness all samples were ensured be approximately 40 nm. Using photoelectron spectroscopy (XPS) combined diffraction (XRD), atoms found...
B4C/Pd multilayers with small d-spacing can easily degrade in the air, and exact degradation process is not clear. In this work, we studied chemical modification of B4C films double layers stored four different environments: a dry nitrogen environment, atmosphere, oxygen-rich wet environment. The XANES spectra placed environment showed most significant decrease σ* states B–C bonds an increase π* B–O compared other samples. X-ray photoelectron spectroscopy (XPS) measurements samples more...
The capacity of Lithium-ion batteries degrades over the time, making accurate prediction their Remaining Useful Life (RUL) crucial for maintenance and product lifespan design. However, diverse aging mechanisms, changing working conditions cell-to-cell variation lead to inhomogeneous cell complicated life prediction. In this work, a data-driven algorithm based on stacked Long Short Term Memory (LSTM) encoder–decoders is proposed RUL encoder upstream decoder form an autoencoder framework...
The geometrical factor in the grazing incident x-ray fluorescence analysis is an important angle-dependent term, which can have a great effect on measured data. In this paper, effects of florescence yield been demonstrated. A formula presented to estimate factor, includes experimental parameters beam and setup. validity proven by good agreement between calculated yields with results analysis.
V/Sc multilayer is experimentally demonstrated for the first time as a high reflectance mirror soft X-ray water window region. It primarily works at above Sc-L edge (λ = 3.11 nm) under near normal incidence while second peak appears V-L 2.42 grazing incidence. The fabricated with d-spacing of 1.59 nm and 30 bilayers has smaller interface width (σ 0.27 0.32 than conventional used Cr/Sc 0.28 0.47 nm). For bilayers, introduction B4C barrier layers little improvement on structure. As number...
Ru/B4C multilayer mirrors are used for hard X-ray monochromators with moderate spectral resolution and high integral flux. To overcome the problem of large compressive stress inherent in multilayers, a reactive sputtering technique using mixture working gas argon nitrogen different partial pressures was tested, fabricated multilayers had period 3 nm. The intrinsic essentially reduced after nitridation relaxed to zero value at approximately 15% pressure gas. Interface roughness slightly...
An on‐chip spectral surface plasmon resonance (SPR) optical sensor with a silver nanoparticle (Ag NP) array has been designed. Dextran (Dex)‐capped Ag NP (Dex‐Ag arrays were initially self‐assembled on the gold (Au) sensing film. The large perturbations and increased penetration depth of evanescent field, which is caused by use Dex‐Ag Au film, can effectively enhance SPR shift response. Compared bare film configuration, configuration improves sensitivity from 5492 to 6613 nm/RIU.
Abstract The microstructure evolution of magnetron-sputtered Ni/C multilayers was investigated by varying the Ni and C layer thickness in region a few nanometers. For samples having 2.6-nm-thick layers, interface width increases from 0.37 to 0.81 nm as decreases 4.3 1.3 nm. Especially for with layers less than 2.0 nm, changes significantly due discontinuously distributed crystallites. 2.8-nm-thick 0.59 when 0.7 microstructures varied is explained based on proposed simple growth model layers.
Short-period (~3.5 nm) Co/C multilayer mirrors are fabricated by the direct current magnetron sputtering technique through addition of a small proportion nitrogen (4-15% partial pressure) to working gas (Ar). The has been demonstrated significantly suppress interdiffusion neighboring materials due nitridation carbon layers as compared with use pure Ar. optimal pressure was found be 6%. At this pressure, provides abrupt interfaces and maximal peak value (19%) s-polarized radiation...
X-ray standing waves generated by periodic multilayers have been used to characterize the interface microstructures of Ti/Ni/Ti trilayers based on reflectivity (XRR) and grazing incidence fluorescence (GIXRF) methods. For Ni layer having thickness 1.7 nm, it is observed that roughness Ti-on-Ni 0.64 nm Ni-on-Ti 0.40 which can be explained an additional induced nucleation crystallites when at amorphous-to-crystalline transition region. 3.3 beyond this region, 0.42 0.46 consistent with...
