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 hybrid system, indicating an enhanced emissive...

Van der Waals heterostructures based on graphene and inorganic two-dimensional (2D) crystals enable exquisite control of interlayer coupling, and emergent electronic and optical phenomena1,2. Extending this concept to organic 2D crystals has been hindered by weak, non-directional interlayer interactions that frustrate...

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 excessive ion accumulation and increase energy consu...
