Electric‐Field Control of Terahertz Response via Spin‐Corner‐Layer Coupling in Altermagnetic Bilayers

Advanced Science, EarlyView.
A spin‐corner‐layer coupling mechanism is proposed in 2D altermagnetic bilayers. Exemplified by NiZrI6, the spin, layer, and topological corner states are simultaneously controlled by an ultralow electric field, enabling active modulation of terahertz absorption, emission, and polarization.

Tuning Desolvation Kinetics with Perovskite‐Type Ion‐Conductive Modulators toward Low‐Temperature Zn Metal Batteries

Advanced Science, EarlyView.
A strategy of constructing perovskite‐type ion‐conductive interphase modulation layer is proposed to break down ion‐dipole interactions of [Zn(H2O)x]2+ to promote Zn2+ desolvation and diffusion kinetics against dendrite growth and active water‐induced hydrogen evolution reactions.

Concentric Perfect Optical Vortex Beam Generated by a Digital Micromirrors Device

IEEE Photonics Journal, 2017
We propose a kind of perfect optical vortex beam (POV) generated via Fourier transformation of Bessel-Gauss (BG) beams through encoding of the amplitude of the optical field with binary amplitude digital micromirrors device.

Diffusion‐Driven Targeted Passivation of Selenium Vacancies via an I‐Doped CdS Buffer Layer for Efficient Sb2Se3 Solar Cells

Advanced Science, EarlyView.
Iodine incorporation into the CdS buffer layer induces spontaneous anion diffusion and selectively passivates selenium vacancies in Sb2Se3 absorbers. The formation of low‐energy, charge‐neutral ISe defects effectively suppresses non‐radiative recombination, resulting in a substantially enhanced open‐circuit voltage and boosting the device efficiency to

Real-Time and In-Flow Sensing Using a High Sensitivity Porous Silicon Microcavity-Based Sensor

Sensors, 2017
Porous silicon seems to be an appropriate material platform for the development of high-sensitivity and low-cost optical sensors, as their porous nature increases the interaction with the target substances, and their fabrication process is very simple ...

Ultrafast Control of Coherent Acoustic Lattice Dynamics in the Transition Metal Dichalcogenide Alloy WSSe

Advanced Physics Research, EarlyView.
Coherent acoustic phonons are generated and optically controlled in bulk WSSe alloy samples using ultrafast spectroscopy. The alloy exhibits a strong coherent acoustic response, which is not an intermediate state between WS? and WSe?. Instead, a much more complex mechanism is proposed.

Metasurfaces and Metadevices for Topological Electromagnetic Waves

Advanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Toroidal‐Dipole‐Driven Polarization‐Selective Quasi‐BICs Enabling Wide‐Angle Near‐Field Image Display in Dielectric Metasurfaces

Advanced Physics Research, EarlyView.
This study presents toroidal‐dipole (TD)‐driven polarisation‐selective quasi‐bound states in the continuum (quasi‐BICs) in all‐dielectric metasurfaces, enabling transverse magnetic (TM)‐selective excitation with ultrahigh quality factors and wide‐angle‐stable polarisation‐dependent near‐field imaging.

Polarization-insensitive integration of nanoparticle-on-a-slit cavities with dielectric waveguides for on-chip surface enhanced Raman spectroscopy

npj Nanophotonics
In the nanoparticle-on-a-slit (NPoS) cavity, a variation of the nanoparticle-on-a-mirror geometry, a metallic nanoparticle is placed on a functionalized narrow slit created on a metal plate so that two nanometric-scale gaps enable extreme plasmonic ...
