Spectral Selective and Low‐Noise Thin‐Film Organic Photodetectors Enabled by Electric‐Field Engineering

open access: yesAdvanced Materials, EarlyView.
Molecular doping redistributes the internal electric field in organic photodetectors, providing a new degree of freedom to spatially control carrier transport and collection. Simulations and experiments reveal distinct transport pathways for injected and photogenerated carriers, enabling low dark current under reverse bias and wavelength‐selective ...

A high-gain, low-noise 3.1–10.6 GHz ultra-wideband LNA in a 0.18μm CMOS

open access: yesMajlesi Journal of Electrical Engineering
An ultra-wideband (UWB) common gate-common source (CG-CS) low-noise amplifier (LNA) in a 0.18μm CMOS technology is presented in this paper. To obtain a high and flat power gain with low noise and good input impedance matching in the entire 3.1–10.6 ...

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Design of low-noise amplifier for MEMS sensors [PDF]

open access: yes
This project focuses on minimizing low-frequency noise and enhancing signal integrity from a common industrial underwater pressure sensor (MS5803-14BA), whose small signal output makes it vulnerable to noise interference.

Radiative Thermal Management for Extreme Environments: Mechanisms and Design Strategies

open access: yesAdvanced Materials, EarlyView.
In this review, we discuss the fundamental mechanisms of radiative cooling and solar heating, material and structural design strategies, hybrid approaches integrating additional heat transfer pathways, and durability‐oriented designs addressing environmental stresses.

Inverse Design of Nanoparticulate Materials

open access: yesAdvanced Materials, EarlyView.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.
