Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Chasing Charge Carriers: Diffusion Dynamics in Mixed‐n Quasi‐2D Colloidal MAPbBr3 Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transport behavior. Three MAPbBr3 morphologies are characterized: nanoplatelets, nanosheets, and nanostripes.

High‐Entropy Magnetism of Murunskite

open access: yesAdvanced Functional Materials, EarlyView.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

Enhanced Electromechanical Response in 1D Hybrid Perovskites: Coexistence of Normal and Relaxor Ferroelectric Phases

open access: yesAdvanced Functional Materials, EarlyView.
The dynamic polarization reversal of coexisting normal and relaxor ferroelectrics in 1D TMAPbI₃ (tetramethylammonium, TMA) is deciphered through combined experimental and theoretical approaches. By bridging atomic‐scale motion, macroscopic polarization switching, and depolarization effects, a universal methodology is established to engineer next ...

Transient Stiffness Patterning in Hydrogels Driven by Dissipative Mechanochemical Coupling

open access: yesAdvanced Functional Materials, EarlyView.
Force‐induced disulfide bond rupture in a polymer‐based hydrogel, coupled with chemical or electrochemical reoxidation, leads to the transient modulation of the hydrogel's stiffness properties. High spatiotemporal control is achieved by this dissipative process, enabling the development of out‐of‐equilibrium stiffness patterns and transient, dose ...
