Ligand‐Mediated Surface Carrier Modulation in Perovskite Nanocrystals for Charge‐Symmetric LEDs

open access: yesAdvanced Materials, EarlyView.
A hydrolysis‐assisted ligand exchange strategy enables surface carrier modulation of perovskite nanocrystals using a multifunctional π‐conjugated ligand. This molecular surface design achieves charge balance and recombination‐zone symmetry in light‐emitting diodes (LEDs), which leads to high‐efficiency perovskite LEDs and establishes a general platform

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

open access: yesAdvanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.
