From Bulk to Colloidal Nanocrystals: Top‐Down Synthesis of Highly Luminescent Cs2ZrCl6:Te4+ Double Perovskite Nanocrystals for X‐Ray Imaging

Advanced Functional Materials, EarlyView.
Top‐down ultrasonication produces highly emissive Cs2ZrCl6:Te4+ nanocrystals (NCs) with a PLQY of 65%, which is higher compared to that of the NCs synthesized by typical bottom‐up hot‐injection synthesis. The colloidal Cs2ZrCl6:Te4+ NCs have been found to be potential candidates for x‐ray scintillation imaging.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Structure‐Guided Balancing of Ambipolar Transport Enables Symmetric Switching in Heterojunction Bilayer Organic Transistor Inverters

Advanced Functional Materials, EarlyView.
Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

Advanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...
