GdIMH (M = S, Se) monolayers: 2D bipolar magnetic semiconductors
In this study, we predict a class of two-dimensional f-electron bipolar magnetic semiconductors, GdIMH (M=S,Se), using first-principles calculations. Monolayer GdIMH has excellent dynamic and thermal...
Mid-infrared ellipsometry for optical critical dimension metrology
Mid-infrared ellipsometry offers a powerful approach for non-destructive optical critical dimension (OCD) metrology in advanced semiconductor manufacturing. This technique supports in-line measurement...
Formation of jets from hemispherical shaped charge liners
Accurately predicting shaped charge jet formation remains a central challenge in detonation physics as analytic models developed for conical liners do not readily extend to alternative geometries used...
Hole transport analysis in N-polar p-GaN
The transport-limiting scattering mechanisms in N-polar p-GaN were identified over a wide range of temperatures (220–770 K), Mg doping concentrations (3 × 1018–4 × 1019 cm−3), and V/III ratios (100–80...
Surface feature retardation in laser-based metal processing via dynamic bimodal beam modulation
Laser-based metal manufacturing techniques, such as laser welding and additive manufacturing, offer high precision and versatility, but the complex melting and resolidification processes often lead to...
Third harmonic-mediated amplification in TWPA
In Josephson traveling-wave parametric amplifiers, higher-order harmonics of the pump tone and its sidebands are commonly present and typically regarded as parasitic. Consequently, most design efforts...
Plane wave configuration for spectroscopic Mueller matrices and diffraction efficiencies of polarization beam splitting metasurfaces at normal and oblique incidence
Transmission polarization beam splitting metasurfaces (MSs) made of dielectric resonators are investigated using diffractive order Mueller Matrix Ellipsometry (MME) in a plane wave configuration using...
Tunable thermal emission and waveguiding by SiC nanowires via collective localized surface phonons
This work investigates the thermal emission from SiC nanowires mediated by collective localized surface phonons (cLSPhs). Specifically, the spectral, directional emissivity of solitary and chains of S...
High-throughput parasitic-independent probe thermal resistance calibration for robust thermal mapping with scanning thermal microscopy
Nanostructured materials, critical for thermal management in semiconductor devices, exhibit a strong size dependence in thermal transport. Studying thermal resistance variation across grain boundaries...
Mode-resolved logarithmic quasiballistic heat transport in thin silicon layers: Semianalytic and Boltzmann transport analysis
Nonequilibrium phonon transport driven by nanoscale hotspot heating in silicon device layers governs heat dissipation in advanced microelectronics and underscores the need for a better microscopic und...
Digitally coded bianisotropic metasurface for direction-dependent elastic wave control
Willis metamaterials are periodic structures with engineered asymmetries that exhibit Willis coupling, a non-classical constitutive behavior linking stress to velocity and momentum to strain. This cou...
Evaluation of structural properties and defect energetics in Al <i>x</i> Ga1− <i>x</i> N alloys
AlxGa1−xN alloys are essential for high-performance optoelectronic and power devices; yet, the role of composition on defect energetics remains underexplored, largely due to the limitations of first-p...
High thermal boundary conductance across a GaN/SiC interface characterized via signal-ratio-based dual-frequency time-domain thermoreflectance
To realize the full potential of GaN high electron mobility transistors (HEMTs), device-level thermal management is necessary by reducing the thermal resistance of the constituent layers, substrate, a...
Optical microcavity structures for time-resolved meso-scale sensing of pressure during shock-compression of heterogeneous materials
Optical microcavity structures (OMCs) exhibit unique spectral responses that can be correlated to externally applied loads, with the potential to be used as time-resolved pressure sensors during dynam...
Muography with symmetric background subtraction
Radiographic analysis of the cosmic muon flux measured by the underground or surface detectors is usually based on the subtraction of the uninteresting background flux, obtained by the Monte Carlo sim...

Scaling behavior of dynamic hysteresis in Bi3.25Pr0.75Ti3O12 thin films
The loop area ⟨A⟩ is related to the applied electric field E and frequency f by a power-law scaling relationship, which can be described as ⟨A⟩∝fa⋅Eb. Many experiments have confirmed that this relatio...
Tunable thermal transport in hole-doped monolayer penta-graphene: A first-principles and machine-learning study
In conventional semiconductors, electron–phonon coupling (EPC) is weaker than phonon–phonon (ph–ph) scattering and plays little role in lattice thermal conductivity (κL). We show, using first-principl...
