Quantum Dot-Induced Kinetic Bottleneck in Singlet Exciton Relaxation of Conjugated Polymer Aggregates

Abstract We designed hybrid aggregate model systems with cascade energy alignment from conjugated polymers (CPs) to quantum dots (QDs) to investigate the effects of QDs on CP singlet (S1) excitons. Radiative recombination of S1 excitons occurs within 1 ps in the chlorinated CP/QD...

Decoupling the Retention–Energy Trade‐Off Through Structural Reorganization of Synaptic Polyelectrolytes for Nonvolatile Neuromorphic Devices

ABSTRACT Electrolyte‐gated synaptic transistors (EGSTs) are promising ion‐mediated artificial synapses, but their performance is constrained by a retention–energy trade‐off. Enhancing long‐term memory (LTM) retention often requires enhanced ion accessibility, which can induce exc...
