Crystallization dynamics of Ge in In/Ge bilayer films under swift heavy ion irradiation: Experimental and density functional theory studies
Indium (In) metal induced crystallization (MIC) of a-Ge in In/poorly crystalline-Ge bilayer thin films under 120 MeV Ni7+ swift heavy ion (SHI) irradiation at different fluences of 1 × 1011, 5 × 1011,...
Zonal multi-shear amount fusion wavefront reconstruction for lateral shearing interferometry in aspheric surface measurement
In lateral shearing interferometry for aspheric surface measurement, the nonuniform fringe density distribution caused by zonal curvature variations degrades wavefront reconstruction accuracy. To addr...
Probing multiphonon luminescence bands in Eu2+-doped thiogallate phosphors via spectral moments approach
Although the method of spectral moments offers unique insight into electron–phonon interactions in activated crystals, it has not been sufficiently exploited to date. Here, we use the spectral distrib...
Observation and characterization of periodic structure formation in dielectric breakdown channels of electron-irradiated polymethyl methacrylate
Dielectric breakdown of insulators is a common failure mode in high-radiation environments and could be used for novel materials processing, but the mechanisms governing channel formation remain poorl...
Tuning the electronic structure of GaN through F/B doping for enhanced Na/K storage: A DFT-based exploration
This study focuses on enhancing the intrinsic electron conductivity of GaN. An innovative approach employing F and B atomic doping strategies was adopted to construct two modified structures, that is,...
Optimizing the upconversion photoluminescence of Er–Nb co-doped Bi4Ti3O12 ceramics by Ti divacancy defects
To optimize the upconversion photoluminescence (UCPL) performance of rare-earth doped Bi4Ti3O12 Aurivillius-phase ceramics, it is critical to reveal the microstructure-property relationship. In this w...
Stress-induced ductile-to-brittle transition of metallic materials: Atomistic simulations and a unified criterion
Existing ductile-to-brittle transition (DBT) criteria often fail to account for the combined effects of stress states and intrinsic material parameters, which are two crucial factors governing failure...
Metal-insulator transition and charge transport mechanisms in SnSe2 field-effect transistor
We report an observation of metal-insulator transition in a thin film of SnSe2. The room-temperature carrier concentration of the SnSe2 film was increased by electrostatic doping to 1.14×1013cm−2. A c...
Magnetic tunnel junction as a real-time entropy source: Field-Programmable Gate Array based random bit generation without post-processing
We demonstrate a method to generate application-ready truly random bits from a magnetic tunnel junction driven by a Field-Programmable Gate Array (FPGA). We implement a real-time feedback loop that st...
Remanence evaluation of silicon steel sheets based on maximum irreversible differential magnetization
Due to the hysteresis phenomenon of ferromagnetic materials, an unknown remanence BR will be generated after the material is disconnected from the power supply, which can cause a considerable inrush c...
Laser-microstructured piezocapacitive system: A wireless platform for quantitative assessment of wound flatness
Postoperative wound management is a critical determinant of recovery in plastic surgery and burn care, where accurate assessment of wound flatness plays a central role. Yet, current evaluation remains...
Revealing secondary particle signatures in muography based on the point of closest approach algorithm
This work reinterprets so-called “noise” in cosmic-ray imaging, indicating that the data of reconstructed Points of Closest Approach (PoCA points) outside the volume of interest defined by traditional...
At wavelength metrology of high-reflectance multilayer mirror in the water window
Multilayer mirrors for the water window spectral range (photon energies from 284 to 543 eV, which correspond, respectively, to the C–K and O–K absorption edges) have become key components for microsco...
Reflection amplitude shape-based approach for low-cost permittivity measurement
The permittivity measurement is important for the characterization of material properties in various applications. Traditional methods, such as the well-known Nicolson–Ross–Weir (NRW) technique, usual...
Structure evaluation of the Ni3GaAs reaction layer formed on a GaAs(001) substrate using transmission electron microscopy
In gallium arsenide (GaAs) semiconductor devices, wafer warpage caused by backside electrode stress complicates wafer handling during subsequent processing and affects device characteristics. Warpage...
Effects of defects on thermal transport across solid/solid heterogeneous interfaces
During the fabrication of heterogeneous structures inside chips, impurities and defects are inevitably introduced. However, the mechanism by which defects affect interfacial heat transport remains unc...
Emergence of anomalous magnetoresistance at low temperatures in Co/Cu nanomultilayers
Magnetic nanomultilayers are promising for spintronic applications owing to their strong response to external stimuli, yet the temperature dependence of their magnetoresistance remains insufficiently...
