Thermal and mechanical behavior of plasma-synthesized, nanometer scale aluminum fluoride passivation layers
Aluminum is highly valued in ultraviolet (UV) optics for its exceptional reflectivity at wavelengths as short as 90 nm, but its effectiveness is compromised by rapid formation of a native oxide layer...
Excimer-laser-annealing-induced crystallization and atomic ordering of Co2Mn0.5Fe0.5Ge Heusler alloy thin films for spintronic applications
Magnetic Heusler alloys are highly attractive for spintronics; however, realizing their full potential requires high-temperature annealing, which is often incompatible with practical device fabricatio...
Subpicosecond thermalization of carriers in polar GaN/AlN quantum dots
We investigate at room temperature the thermalization and recombination dynamics of near-resonantly photogenerated carriers in c-plane GaN/AlN wurtzite quantum dots (QDs) using time-resolved photolumi...
The Sareh twist: A hidden geometric principle in origami tessellations
Origami techniques originate from the ancient paper-folding traditions of China and Japan. Since the mid-20th century, origami engineering has developed into an independent technology, transforming co...
Pulse formation and spectral broadening in continuous-wave optical parametric oscillator with dispersion control
We report the initiation of pulse formation and significant spectral broadening in a continuous-wave (cw)-pumped optical parametric oscillator (OPO) in a degenerate doubly resonant oscillator (DRO) co...

Charge transport and positively charged defects in Ta2O5/SiO2 dielectric stacks
The electrical properties of Ta2O5/SiO2 stack structures are investigated, focusing on charge transport and the presence of positively charged defects. Capacitance–voltage (C–V) and triangular voltage...
Harnessing orbital angular momentum in solids from electrons to quasiparticles
Spintronics has advanced memory and logic technologies by utilizing the electron's spin degree of freedom. In contrast, the electron's orbital angular momentum (OAM) was long regarded as quenched in t...
Chiral anomaly bulk states in acoustic S-graphene with multiple Dirac points
Dirac points (DPs) lie at the core of topological physics. Beyond robust in-gap edge states, chiral-anomaly bulk states (CABSs) induced by finite-size effects enable resilient bulk transport. Extendin...
A point-particle-based hydride shell-shedding model for ejecta particle transport in reactive environments
A shock wave passing over a rough or perturbed metal surface will induce a limiting case of Richtmyer–Meshkov instability and will cause small particles to eject from the surface and transport into th...
Experimental and numerical investigations of ionic electrospray thruster beam in vacuum chamber
This paper presents a correlated experimental and simulation study of an ionic electrospray thruster beam. The effects of vacuum chamber on the thruster beam are inferred through comparisons of labora...
Dual quasi-bound states in the continuum in terahertz metasurfaces for high-Q resonance and multi-modal behavior
Bound states in the continuum (BICs) suppress radiative leakage and enable high-Q resonances for terahertz (THz) photonics. Here, we propose a metallic quadrumer metasurface in which dual quasi-BICs a...
Numerical simulation of effective dielectric constant of MXene films
MXenes are two-dimensional carbides and nitrides that are relatively simple to manufacture. Even when very thin and flexible, their films can replace metals in many devices, such as electromagnetic sh...
Near-field thermal radiation between deep subwavelength membranes driven by corner and edge modes
We demonstrate that the thermal radiation between deep subwavelength membranes of silicon carbide (SiC) exhibits a maximum enhancement over that of infinite SiC surfaces separated by the same vacuum g...

Effectiveness of fluorine termination at nitrogen vacancies inside gallium nitride crystals based on first-principles calculations
Nitrogen (N) vacancies inside gallium nitride (GaN) crystals can scatter carriers and degrade the performance of GaN-based devices. Hydrogen (H) termination is an effective approach for eliminating de...
3D printing technologies for metasurface fabrication and applications of metasurfaces manufactured by 3D printing processes

Length-dependent electron–phonon nonequilibrium thermal resistance in metal–insulator superlattices
When heat flows across a metal–insulator interface, it must be transferred between electrons and phonons at a certain length scale that depends on the electron–phonon coupling characteristics. This no...
