Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

3D Nano‐architected Polymer Shell Enables Reconfigurable Stabilized Blue Phase Soft Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Spherical polymer shells featuring nanostructure of blue phase (BP) disclinations form via in situ photo‐polymerization within BP liquid crystals, providing controlled anchoring for BP nucleation and growth at room temperature and beyond. This architected confinement enhances BP thermal stability over a broad temperature range while enabling dynamic ...

Solution‐Processable and Ambient‐Stable Highly Conductive p‐Type Polymers Derived from Dihydropyrazine and Ethylenedioxythiophene

open access: yesAdvanced Functional Materials, EarlyView.
This work presents π–conjugated polymers based on dihydropyrazine (DHP) and ethylenedioxythiophene (EDOT), developed to produce highly conductive, flexible films for printed electronics. By optimizing the DHP and EDOT ratio, strong and compact π–π stacking is achieved, resulting in polymer films with conductivities up to 1700 S cm−1 under ambient ...

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

Self‐Poled Halide Perovskite Ruddlesden‐Popper Ferroelectric‐Photovoltaic Semiconductor Thin Films and Their Energy Harvesting Properties

open access: yesAdvanced Functional Materials, EarlyView.
Low‐dimensional halide perovskite thin films, (BA)2(MA)n‐1PbnBr3n+1 (n = 1, 2), exhibit both semiconducting and ferroelectric properties, enabling mechanical and light energy harvesting. Using Cr/Cr₂O₃ or PCBM as barrier layers ensures reproducible ferroelectricity.
