Broadband reflective elastic mode conversion enabled by a single row of inclined long-slits
Broadband longitudinal-to-transverse mode conversion under normal incidence remains difficult to achieve, especially with structurally simple designs. Numerical simulations show that a single periodic...
Self-organized metasurface enabling negative photoconductance and memristive behavior via van der Waals interaction
Negative photoconductance (NPC) and memristive behavior have been observed simultaneously in planar, metal-oxide-based heterojunctions. Self-organized TiO2 crystalline metasurface thin films were prep...
Investigation of dynamic evolution and emission pattern transition in an atmospheric pressure surface micro-discharge
This study investigates the dynamic evolution and emission pattern transition of atmospheric-pressure helium surface micro-discharges using optical emission spectroscopy and electrical measurements. U...
Cut-enabled anisotropic and non-reciprocal elasticity in chiral metamaterials
We introduce strategically placed cuts into chiral mechanical metamaterials to achieve strongly anisotropic and static non-reciprocal elasticity in a fully passive architecture. Under loading, the cut...
Electronic thermal conductivity of doped Rashba–Floquet <i>d</i> -wave altermagnets
Altermagnets, a novel class of collinear magnets with momentum-dependent spin splitting and zero net magnetization, offer unique opportunities for tunable thermal transport. Here, we investigate the e...
Impact of carrier injector design on the threshold of interband cascade lasers
We theoretically investigate how the injector region design of interband cascade lasers (ICLs) impacts the threshold carrier and current densities. The model combines a polarization-sensitive 8-band k...
Geometry-induced sensitivity enhancement in unconventional nano-SQUID architectures
Superconducting Quantum Interference Devices (SQUIDs) represent a cornerstone of nanoscale metrology, offering unparalleled magnetic field sensitivity across diverse scientific and technological front...
Role of structural asymmetry in tailoring electromagnetically induced transparency and figure of merit in terahertz metamaterials
Electromagnetically induced transparency (EIT) in metamaterials, a classical analog of quantum EIT, exhibits a sharp transparency window with steep dispersion, enabling applications such as sensing an...
Voltage controlled magnetic anisotropy at iron/spinel oxide interfaces
The ability to use an applied voltage to effectively manipulate perpendicular magnetic anisotropy is critical for high density, robust magnetic random access memory devices. Using first principle simu...
Radiation tolerance of Ga2O3 for harsh environment applications: Neutron irradiation and defect studies
Gallium oxide (Ga2O3) has emerged as a promising material for high-power and radiation-tolerant electronics due to its ultra-wide bandgap and excellent thermal stability. In this study, single-crystal...
Validity of one-dimensional evaporation model for confined microchannels
Evaporation lies at the heart of many industrial processes, ranging from power generation, thermal desalination, to advanced cooling systems. These technologies leverage the efficient mass and heat tr...
Stability analysis of doped carbon nanotubes (CNTs)
It is well established that (3, 0), (3, 3), and (5, 0) carbon nanotubes (CNTs) are experimentally confirmed and are superconducting at low temperatures. In this study, the dynamical stability of (5, 0...
Current shunting and plasma instabilities during electrical explosions of copper and aluminum wires in water and air
We present the first x-ray images of electrically exploding wires in air and water, captured at the European X-ray Free-Electron Laser (EuXFEL). These images reveal current shunting in a copper wire d...

We investigate the electrical transport and low-frequency noise (LFN) characteristics of hydrothermally grown n-type ZnO nanorod/nanotextured film homojunctions synthesized via chemical bath depositio...
Superlattice reflection signatures of the insulator–metal transition in V3O5 thin films
Nanoelectronic systems that are inspired by the brain are increasingly looking to insulator–metal transition (IMT) materials as they can mimic the response characteristics of neurons to temperature ch...
Imitating neuro-plasticity in SrTiO3 based synaptic optoelectronic memristor for in-memory computing applications
Recently, perovskite oxide-based synaptic optoelectronic memristors (SOMs) present a favorable path toward the advancement of neuromorphic (or in-memory) computing. In this study, we propose a SrTiO3...
