Gate‐Programmable Linearization of Atomically Thin Nanoelectromechanical Resonators via Duffing Nonlinearity Cancellation

Advanced Functional Materials, EarlyView.
Gate bias is used to cancel Duffing nonlinearity in atomically thin MoS2 drumhead resonators, switching their response from hardening to softening and creating a nearly linear operating point. This electrical control suppresses hysteresis, enables stronger linear drive, and improves signal‐to‐noise ratio, offering a practical route to stable 2D NEMS ...

A Material‐Agnostic Strategy for Uniform Patterning of Conjugated Polymers Unveils the True Role of Porosity in Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
A generalizable strategy for fabricating regular porous, chemically intact conjugated polymer channels reveals how porosity benefits organic electrochemical transistors. Composition‐dependent performance enhancement is linked to charge carrier mobility, volumetric capacitance, and effective doped volume.
