Vacuum facility neutral flux analysis
Understanding neutral flux behavior within vacuum facilities is important for characterizing the facility effects and design. For applications such as electric propulsion (EP), thruster behavior, perf...
Thermal gradient-driven skyrmion dynamics with suppressed skyrmion Hall angle
Thermal-gradient-driven skyrmion dynamics offers a promising route to green spintronics, enabling the utilization of waste heat by information transport and processing. Using micromagnetic simulations...
Effects of discharge power for magnetron sputter deposition of boron carbide films on tilted substrates
High-rate growth of B4C films with low residual stress and nodular defect density remains a challenge. Here, we use a 75-mm-diameter full-face erosion magnetron source operated in the direct-current m...
Thermally insensitive and polarization tunable metamaterial absorbers enabled by one-dimensional saline-water gratings
A simple liquid-based metamaterial absorber, featuring a one-dimensional subwavelength grating incorporated with the saline water, has been proposed and investigated. Numerical simulations and experim...
Hole concentrations in doped gray <i>α</i> -Sn on InSb and CdTe measured with infrared ellipsometry
Gray tin (α-Sn) layers with 30 nm thickness were grown on InSb (001) substrates using molecular beam epitaxy. The surface preparation of the substrates was adjusted to achieve either n-type or p-type...
Controllable dual auto-focusing electron Pearcey Airyprime beam
In this paper, a new type of electron Pearcey Airyprime beam (EPAPB) is proposed and its propagation characteristics in free space and in a constant magnetic field are numerically studied. In free spa...
Unraveling the effect of grain size distribution on tension-compression asymmetry of polycrystalline NiTi shape memory alloys
The tension-compression asymmetry of nanograined NiTi shape memory alloy (SMA) under different loading modes is well recognized, yet how grain size distribution governs this asymmetry remains to be el...
Strain-driven amorphization in Al1− <i>x</i> Y <i>x</i> N thin films and lattice-engineering stabilization illustrated by In1− <i>x</i> Y <i>x</i> N
Aluminum yttrium nitride (Al1−xYxN) is known to grow amorphous at relatively low Y concentrations (x ∼0.3), but the exact structural origin of this transition has not been examined at the nanoscale. I...
Alloy-induced elastic heterogeneity driving subharmonic acoustic generation in nanofluids
Subharmonic generation in acoustically driven fluids provides a sensitive probe of nonlinear wave–matter interactions and material heterogeneity. Here, we report a systematic experimental investigatio...
Structural, transport, and superconducting properties of Ir-doped Nb2− <i>x</i> Ir <i>x</i> PdSe5
We present a systematic study of the structural, normal-state transport, and superconducting properties of Ir-doped Nb2PdSe5 with nominal composition Nb2−xIrxPdSe5. Powder x-ray diffraction confirms t...
Naturally resonant emitters: Approaching fundamental antenna limits
Antenna miniaturization remains a critical technological challenge across frequency scales—from microwave RF links in phones/wearables to VLF (3-30kHz)/ELF (3Hz-3kHz) for underwater-to-air communicati...
