Experimental study of high-energy single-pulse nanosecond discharges in pin-to-pin configuration
Single-pulse pin-to-pin nanosecond pulsed discharges in ambient air (gap distances of 3–7 mm) were investigated at high pulse energies (∼20–30 mJ deposited energy per 11 ns full width at half maximum...
Glassy lattice thermal conductivity of Li6PS5X (X = Cl, Br, I) argyrodites from first principles
We compute lattice thermal conductivities of Li6PS5X (X = Cl, Br, I) argyrodites from first principles within the Wigner transport formulation. We find that these systems are afflicted by unstable vib...
Deep operator network-based black-box DC arc model and its parameter identification
Direct current (DC) arcs frequently occur in DC power systems, and accurate modeling of their behavior is essential for enhancing system safety and reliability. Traditional arc models often suffer fro...
Structural optimization of lattice-matched Sc0.14Al0.86N/GaN superlattices for photonic applications
ScxAl1−xN is an emerging III-nitride material known for its high piezoelectric coefficient and ferroelectric properties. Integration of wide-bandgap ScxAl1−xN with GaN is particularly attractive for q...
Tuning colossal magnetoresistance through A-site ionic radius in polycrystalline Gd0.5Ca0.5−<i>x</i>Sr<i>x</i>MnO3 (<i>x</i> = 0.0–0.5) systems
The magnetotransport properties of polycrystalline Gd0.5Ca0.5−xSrxMnO3 systems reveal a significant enhancement in magnetoresistance with increasing A-site ionic radius, transitioning from “Ca” to “Sr...
Low-energy-barrier ferroelectric in monolayer CdX (X = Se and Te) and their potential applications in electrical device and photocatalyst: A first-principles study
Ferroelectric materials exhibit switchable spontaneous polarization and provide significant potential in advanced electronics. This study employs density functional theory to investigate two-dimension...
Boron nitride thin film synthesis with a ns-pulsed MHCD: <i>In situ</i> plasma diagnostics and post-growth film characterization
Boron nitride (BN) is deposited on a Si 〈100〉 wafer (≈20 cm2) via plasma enhanced chemical vapor deposition (PECVD) using a ns-pulsed N2/Ar micro hollow cathode discharge (MHCD) as a microplasma sou...
Impact of particle number and cell size on energy-conserving PIC applied to RF-driven bounded plasmas
Recent studies have shown that variations in particle-per-cell count and cell size can significantly affect the accuracy of 1D implicit energy- and charge-conserving electrostatic particle-in-cell sim...
Nonlinear electronic polarizations and anharmonic phonon couplings in ferroelectric perovskite compounds
Based on the least action principle, we use first-principles calculations to analyze continuous switching paths of the ferroelectric modes in ferroelectric perovskite compounds at zero macroscopic ele...
Machine learning-based prediction of spatially and frequency-selective optical field coupled absorption in random metasurfaces
Achieving frequency and spatially selective optical field coupling represents a crucial avenue for simplifying metasurface architectures. Given the intricacy of promptly analyzing the optical properti...
Self-sharpening penetration model of tungsten high entropy alloy
Long-rod projectiles (LRPs) with deep penetrability have been widely used in the defense industry. LRPs made of self-sharpening materials can maintain a sharp head due to the formation of shear bands...
