Advanced Functional Materials, EarlyView.Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

A Frequency Locked Loop Using a Phase Frequency Detector
The Journal of Korean Institute of Electromagnetic Engineering and
Science, 2017 논리회로로 구성된 위상주파수 검출기(Phase Frequency Detector: PFD)는 집적회로 구현의 용이성으로 인해 위상잠금회로(Phase Locked Loop: PLL)에 널리 사용되고 있다. 반면, 주파수 잠금회로(Frequency Locked Loop: FLL)는 PLL에서 기준발진기를 제거하고 공진기가 기준발진기 역할을 하는 구성이다.

Electroactive Liquid Crystal Elastomers as Soft Actuators
Advanced Functional Materials, EarlyView.Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

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.
