Reconstructing Quantum Dot Surfaces via Dual‐Functional Ligand Pairing Enables Efficient Shortwave Infrared Optoelectronics

Advanced Functional Materials, EarlyView.
This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.

n‐Type Semiconductor Hydrogels for Tunable Organic Electrochemical Transistors Operation and Evaporation‐Driven Synergistic Energy Harvesting and Thermal Management

Advanced Functional Materials, EarlyView.
This study develops a tunable n‐OSC hydrogel (PBFDO‐PAAc) platform with a tunable porous network and thermoelectric properties. It demonstrates the first report of n‐OSC hydrogels for evaporation‐driven hydrovoltaic‐thermoelectric electricity generation as well as chemically dedoping‐mediated OECT working mode reconfiguration. This work expands n‐OSCs’

Unusual Temperature‐Enhanced Bulk Photovoltaic Effect Beyond the Centrosymmetric Phase in CuCrP2S6 van der Waals Crystals

Advanced Functional Materials, EarlyView.
Contrary to conventional expectations, the bulk photovoltaic effect in CuCrP2S6 is enhanced rather than suppressed upon transitioning into the crystallographically centrosymmetric phase. Dynamic Cu‐ion disorder creates transient polar states, which substantially amplifies zero‐bias photocurrent (shift‐current) generation, establishing dynamic symmetry ...
