Directional dependence of thermoelectric properties in Na2AgAs: Contributions of in-plane rattling and multiple energy valleys
The thermal transport and thermoelectric properties of Na2AgAs are rigorously explored through first-principles calculations, incorporating phonon self-consistent theory and Boltzmann transport equati...
Unveiling vibrational and optoelectronic properties of HfX2 (X = Br, I) monolayers via DFT calculations
The optoelectronic properties, phonon dispersion, stability, and quantum dynamics of HfX2-type transition-metal dihalides (TMDHs) were systematically investigated using first-principles calculations b...
Improving electrical contact of vertically aligned carbon nanotubes with bonding metals in thermocompression bonding through oxygen plasma treatment
Vertically aligned carbon nanotubes (VACNTs) are being widely studied due to their exceptional mechanical, electrical, and thermal properties. The application of thermocompression bonding (TCB) techni...
Switching BIC through polarization of incident light on bilayer malposed photonic crystal slabs
Bound states in the continuum (BICs) are initially regarded as special modes of structure and independent of external conditions. The dynamical modulation of BICs or quasi-BICs is based on the tuning...
High-rate magnetron sputter deposition of low-stress boron carbide films on tilted substrates
Boron carbide is attractive for several applications, including nuclear fuel capsules for inertial confinement fusion (ICF). The fabrication of ICF capsules involves the deposition of ultrathick coati...
Rough surface heterogeneous influence on rarefied gas flow in single rock fractures
Rarefied gas flow in rock fractures governed by Knudsen flow is employed in residual gas capture and storage. Previous studies mainly adopted the classical theory under the continuum hypothesis to des...
Origin of the 3.45 eV emission in GaN nanowires traced to oxygen-induced surface defects and suppressed by AlN coating
The demand for GaN nanowires (NWs)-based optoelectronic devices has rapidly increased over the past few years due to their superior crystalline quality compared to their planar counterparts. However,...
Muon tomography for cultural heritage objects
Cultural heritage conservation increasingly relies on non-destructive techniques and imaging methods based on the absorption or scattering of photons (X or γ-rays) or neutrons. While these techniques...
Characterization of thermal boundary conductance of 2D–3D van der Waals interface using wideband transducerless frequency-domain thermoreflectance
Thermal boundary conductance (TBC) of van der Waals (vdW) interfaces plays a crucial role in thermal dissipation in devices based on two-dimensional (2D) materials, affecting both device performance a...
Dual-wavelength terahertz metasurface capable of amplitude and phase modulation for wavefront manipulation and holography
This study presents a comprehensive investigation of a terahertz metasurface capable of simultaneous amplitude and phase modulation. We propose two distinct amplitude modulation approaches based on re...
Thermal strain management of III–V heterostructures grown on InP-on-silicon (InPoSi) substrates
Hetero-integration of InP-based compound semiconductors on CMOS-compatible silicon is desirable for low-cost large-scale applications. Recently, an approach consisting of integrating a thin InP buffer...
