Crystallinity Effects on Near‐Infrared Photoresponse in Y6‐Based Organic Phototransistors

open access: yesSmall, EarlyView.
Solution‐processed Y6 thin films are investigated as active layers of organic field‐effect transistors and as near‐infrared photodetectors. Enhanced crystallinity in Y6 films induced by thermal annealing leads to improved charge transport and pronounced photoresponsivity.

Morphological Stabilization of CsPbBr3 Quantum Dot Films Enabled by PVC‐g‐PMMA Graft Copolymer Encapsulation for Water‐Robust Color Conversion

open access: yesSmall, EarlyView.
Poly(vinyl chloride)‐graft‐poly(methyl methacrylate) encapsulation enabled formation of water‐stable CsPbBr3‐quantum‐dot fims with enhanced photoluminescence (PL) retention upon exposure to water, UV radiation, and ethanol. Time‐dependent ex situ transmission electron microscopy with quantitative particle segmentation identified the coefficient of ...

Anisotropic Thermal Properties of Electrically Insulating Thin Films and Sheets: A Review

open access: yesSmall Methods, EarlyView.
Thermally conducting and electrically insulating materials with anisotropy properties play an integral role in advanced thermal management, in particular for electronic devices. This review discusses recent progress in enhancing thermal conductivity and controlling the thermal anisotropy between in‐plane and cross‐plane (through‐thickness) directions ...

Sensitivity Analysis of Short‐Term Frequency Stability to Post‐Contingency Active Power Increase and Support Duration from Deloaded Wind Turbines

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The growing deployment of Type‐4 wind turbine generators (WTs), driven by carbon neutrality and net‐zero policies, may challenge frequency stability in power systems. Unlike synchronous generators, WTs connected to the power system via converters do not provide inertia.

Active Power Control of Full‐Scale Converter‐Based Wind Turbine Considering Turbine Angular Velocity for Short‐Term Frequency Stability in Power Systems

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The increasing deployment of wind turbine generators (WTs) may alter the frequency stability of power systems. Unlike traditional synchronous generators, WTs are connected to the power system through converters. Consequently, WTs cannot provide an inertia response to the power system. Nevertheless, the converters can perform rapid control.
