Design of a wide band metasurface as a linear to circular polarization converter

Modern Physics Letters B, 2017
In this paper, we present a wide band metasurface (MS) polarization converter which converts a linearly polarized signal to a right-handed or left-handed circularly polarized signal both numerically and experimentally. The unit cell of MS has three nested rectangular resonators which have two metallic patches at its crossed corners.

Exciton Binding Energy of Phosphorescent Emitter Molecules in Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Energy level alignment is key to efficient OLED design, yet determining LUMO energies remains challenging. A methodology based on field‐induced dissociation and kinetic Monte Carlo simulations is presented to extract LUMO energies of iridium‐based phosphorescent emitters from their exciton binding energy.

Full Stokes Mid-Wavelength Infrared Polarization Photodetector Based on the Chiral Dielectric Metasurface

Photonics
Conventional imaging techniques can only record the intensity of light while polarization imaging can record the polarization of light, thus obtaining a higher dimension of image information.

The Ni,Cd Heteroatoms‐Initiated Synergistic Tuning of Electron Configuration in Fe2VO4 Nanosheets Electrocatalysts to Profoundly Stabilize Alkaline Seawater Electrolysis

Advanced Functional Materials, EarlyView.
A Ni,Cd‐codoped Fe2VO4/NF bifunctional electrocatalyst is rationally designed for efficient seawater electrolysis. Synergistic effect modulates electron configuration, optimizes intermediates adsorption, stabilizes high‐valence Fe/V sites, and repels chloride ions to suppress corrosion and side reactions, thus contributing to performance improvement of

Large Transverse Thermoelectric Effect in Weyl Semimetal TaIrTe4 Engineered for Photodetection

Advanced Functional Materials, EarlyView.
This experimental work shows that the anomalous scanning photocurrent response patterns of the Weyl semimetal TaIrTe4${\rm TaIrTe}_4$ under visible and long‐wave infrared illumination are due to a large transverse thermoelectric response of the material.
