Fiber-Optic Sensor-Based Remote Acoustic Emission Measurement in a 1000 °C Environment
Sensors, 2017 Recently, the authors have proposed a remote acoustic emission (AE) measurement configuration using a sensitive fiber-optic Bragg grating (FBG) sensor. In the configuration, the FBG sensor was remotely bonded on a plate, and an optical fiber was used as ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Advanced Functional Materials, EarlyView.Topological van der Waals contacts represent a new class of electrodes for 2D semiconductors, enabling precise control of the Schottky barrier height (SBH) and contact resistance (RC) through interlayer distance and orbital hybridization engineering. In Se‐based transition metal dichalcogenides, these contacts achieve an ultralow SBH of 7 meV, RC of 0.

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response
Advanced Functional Materials, EarlyView.This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...

利用导波震相分析阿拉斯加俯冲带东端Yakutat地体的洋壳结构特征
Dizhen xuebao低速俯冲洋壳附近震源激发的部分地震波被困在低速层内以导波传播，弧前地震台站所记录的导波可用于洋壳结构成像。阿拉斯加俯冲带具有丰富的地震事件且布设了相对密集的永久性地震台站，为利用导波探测洋壳结构提供了天然试验场。本文对区域密集台站记录到的阿拉斯加俯冲带东端Yakutat地体两侧中源地震事件的导波震相传播特征进行了深入分析。结果显示：阿拉斯加俯冲带东端的Yakutat地体范围内，受低速俯冲洋壳影响的导波震相到时延迟随传播距离的增大而增加 ...
