Stress-induced diffusion suppression and defect-related B-mode breakdown in thermal SiO2 on Czochralski silicon
We present an analytical model describing the degradation of the dielectric breakdown field in thermal SiO2 films grown on Czochralski (CZ) silicon substrates containing void-type defects, such as cry...
Tamping-induced densification and transient phase transformation in heterogeneous Ni–Al cold spray: An atomic-scale study
Current cold spray research relies predominantly on simplified single-particle impact models, which cannot capture the critical effects of multi-particle interactions and complex thermal histories on...
Study of the plasma dynamic response mechanism of Q235 steel under magnetic field-assisted combined laser irradiation
This study investigates magnetic field-assisted combined laser irradiation of Q235 steel, constructing a two-dimensional coupled simulation model integrating the two-temperature model and magnetohydro...
Investigating grain boundary segregation in latent space via dimensionality reduction and descriptor-based interfacial diagrams
We perform hybrid molecular dynamics/Monte Carlo simulations to investigate Ag segregation at representative Cu Σ5 grain boundaries (GBs) and compute smooth overlap of atomic positions (SOAP) vectors...
A non-Foster superconducting broadband matching network
The nonlinear inductance of the Josephson junction has enabled the development of a wide range of continuous-variable amplifiers and qubit-based devices with unprecedented sensitivity. We present an a...
All-optically controlled artificial synaptic device based on PZT photochromism for biomimetic visual memory imaging systems
Neuromorphic vision systems are critical for high-efficiency edge intelligence, yet mainstream electrically controlled synaptic devices suffer from irreversible ion migration and poor biomimetic imagi...
Octave-spanning terahertz quarter-wave plates based on over-coupled Fabry–Pérot resonances in reflective metal–dielectric–metal metasurfaces
Compact devices for broadband polarization control in the terahertz (THz) regime remain challenging to realize due to the intrinsic phase dispersion associated with birefringent materials and resonant...
Fabry–Pérot quasi-bound states in the continuum-enabled active terahertz absorption in bulk Dirac semimetal metasurface
Actively tunable terahertz absorbers featuring both high quality factors and spectral stability are highly desirable for narrowband modulation and sensing, yet achieving these two properties simultane...
Effects of shock-induced α (bcc) → ɛ (hcp) phase transition on spall failure in Fe–Mn alloys
Plate-impact experiments were conducted on Fe–Mn alloys containing 4, 7, and 11 at. % Mn to investigate the role of shock-induced α(bcc) → ɛ(hcp) phase transformations on wave dissipation and subseque...
A self-consistent field–matter approach for pump–probe measurements in ultrafast materials
Quantitative interpretation of ultrafast pump–probe experiments requires a consistent treatment of the excitation stage, particularly under strong optical pumping where absorption saturation and inter...
Low-frequency and broadband waterborne muffler based on low acoustic impedance arc-shaped metamaterials
Low-frequency noise control in ship seawater pipeline systems remains challenging, as mufflers are required to deliver good broadband performance within compact spaces. Inspired by bladder mufflers th...
Determination of the mass transport parameters in thin membranes by phase-sensitive photoacoustics in the optically transparent and mixed regimes
The research complements and extends the scope of the work reported in “LED-based multibeam photoacoustics combined with electrical circuit-based modelling for the analysis of multispecies mass transp...
Tunable extinction and near-perfect absorption in graphene plasmonic terahertz metasurfaces
An extinction-centered framework is established for designing tunable graphene plasmonic metasurfaces in the terahertz (THz) regime. A deeply subwavelength, radially symmetric graphene resonator is an...
Nonradiative carrier capture by point defects in irradiated GaN
In this work, accurate electronic structure calculations are employed to investigate key radiation-relevant defects in gallium nitride, including point defects (vacancies, interstitials, and antisites...
Polarity control of sputter-deposited wurtzite AlScN thin films by AlSc seed layer
The effect of a thin-AlSc seed layer on the polarity of the ferroelectric Al0.87Sc0.13N films was investigated. The polarity of AlScN films was evaluated through measuring capacitance responses of met...
Effect of fractional heat-transport operators on the photoacoustic response of aluminum
This work investigates the influence of fractional heat-transport operators on the amplitude and phase delay of the photoacoustic signal measured in aluminum samples under transmission geometry using...
