The calculation of keyhole depth based on the primary absorption of front keyhole wall in laser deep-penetration welding
The establishment of an accurate prediction model of keyhole depth during laser welding is of great significance for predicting the weld depth or pre-selecting suitable welding process parameters. In...
Roadblocks to ambient-pressure room-temperature superconductivity in lutetium hydrides
Recently, the reports of room-temperature superconductivity in nitrogen-doped lutetium hydrides at near-ambient pressure (1 GPa) have attracted considerable interest but remain controversial due to th...
Symmetry breaking-induced resonances with more efficient terahertz reflections
We report our experimental observation and theoretical and numerical validation of a new type of THz resonance and bandgap induced by symmetry breaking in a periodically corrugated parallel plate wave...
Synergistic effect of Fe etching and Ar+ bombardment on the electron field emission properties of single-crystal diamond
A new strategy coupling Fe etching with Ar+ bombardment was proposed and carried out on the single-crystal diamond (SCD) surface for enhancing the electrical properties of diamond by the dual effects...
Depth-resolved measurements of magnetic domains in grain-oriented electrical steel
A new method for obtaining depth-resolved measurements with an x-ray magnetic circularly polarized emission (XMCPE) microscope is reported in this work. Depth-resolved observations of magnetic domains...
Comparative study of doping properties and the effect on sliding barriers in γ-InSe
As the sliding ferroelectricity (SF) emerges as a potential approach to develop low-power ferroelectric electronics, fabricating high-quality SF van der Waals (vdW) crystals is of great importance. Fo...
Unified description of electron spin relaxation in (110)-oriented III–V semiconductor quantum wells
III–V semiconductor quantum wells (QWs) with (110) orientation are expected to serve as a platform for spintronic devices due to their ability to exhibit prolonged electron spin-relaxation times to th...
Reflectometry technique for study of complex multilayer micro- and nanostructures with lateral periodicity
This study introduces a reflectometry-based technique for characterizing complex thin-film structures with lateral periodicity, using only a single, large-beam measurement to capture essential structu...
Fabrication of PbSe quantum dot based flexible photodetector device arrays
Near-infrared spectroscopic detection has attracted great attention due to its extensive applications in various fields. Colloidal quantum dots exhibit significant potential for flexible and large-sca...
Cartesian multipole expansion for millimeter-wave metasurfaces design
Metasurfaces in the microwave and millimeter-wave frequency ranges are conventionally designed through trial-and-error approaches using full-wave electromagnetic simulation packages that rely on discr...
Exceptional ballisticity in monolayer BX (X = P, As, Sb) transistors
The initial excitement surrounding the potential use of two-dimensional (2D) semiconductors as a replacement for bulk silicon in ultra-thin body transistors has somewhat diminished due to their inferi...
Structural behaviors of lead zirconate titanate-based ferroelectric ceramics during pyroelectric-power generation cycles
Energy harvesting from waste heat can improve energy efficiency in society. This research investigated the structural behaviors of lead zirconate titanate–based ferroelectric ceramics using operando n...
Theoretical insights into the thermoelectric performance of 2D MXene Ti3C2
A class of two-dimensional (2D) materials known as MXenes has a layered structure and is expected to exhibit unique thermoelectric (TE) properties. Despite the high expectations for certain MXenes’ TE...
