Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

Advanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Bio‐Derived Polyelectrolyte Additive–Induced Interfacial Ion‐Diffusion Barriers for Nonvolatile Organic Artificial Synapses

Advanced Functional Materials, EarlyView.
Sodium alginate regulates interfacial ion transport and retention in electrolyte‐gated synaptic transistors. The carboxylate‐rich polymeric network forms a dynamic interfacial ion‐diffusion barrier that facilitates ion injection during programming while suppressing ion back‐diffusion, thereby stabilizing the electrochemically doped channel state.
