Cu─X Bonds Regulated Conduction and Polarization Loss in Conductive Metal‐Organic Framework Under Electromagnetic Field

Advanced Science, EarlyView.
A ligand regulation strategy by modifying functional motifs (X = −NH2, −OH, and −SH) in triphenylene is pioneered and developed to afford Cu─X bonds, achieving a synergistic conduction and polarisation loss mechanism under an electromagnetic field for enhanced electromagnetic wave absorption. Abstract Conduction and polarization are known to profoundly

Obstacle‐Immune Microwave Wireless Power Transfer System Based on Amplitude‐Dependent Caustic Metasurface

Advanced Science, EarlyView.
This paper innovatively proposes an advanced microwave wireless power transfer (MWPT) system based on the amplitude‐dependent caustic metasurface generating the circular Airy beam. The proposed MWPT system will advance the research and development of circular Airy beams in the radio frequency domain.

Charge Injection and Transport in an Isoindigo‐Based Polymer Transistor

Advanced Electronic Materials, EarlyView.
This study presents the charge injection and transport properties of field‐effect transistors based on an isoindigo‐bithiophene donor‐acceptor polymer semiconductor contacted with thiolated self‐assembled monolayer (SAM)‐functionalized electrodes. Temperature‐dependent contact characteristics are measured and simulated.

Bi2O2Se/Ta2NiSe5 Tunneling Heterojunction for High‐Performance, Polarization‐Sensitive, and Broadband Infrared Photodetector

Advanced Electronic Materials, EarlyView.
An optimal dynamic balance between carrier lifetime and transit time is achieved in the Bi2O2Se/Ta2NiSe5 tunneling heterojunction, which simultaneously attains high responsivity (>103 A W−1) and a fast response time (≈5 µs). The specific detectivity can reach 3.75 × 1013 Jones at 633 nm and 1.8 × 1010 Jones at 1550 nm. Abstract New technologies such as
