Field‐Effect Transistors from Artificial Charged Domain Walls in Stacked Van der Waals Ferroelectric α‐In2Se3

open access: yesAdvanced Materials, EarlyView.
This study utilizes the van der Waals stacking of ferroelectric α$\alpha$‐In2Se3 to fabricate in‐plane artificial charged domain walls. These charged domain walls are electrically accessible, gate‐tunable, and show 2–9 orders of magnitude higher conductance than charged domain walls from thin film ferroelectrics, allowing their integration in field ...

Engineering Active Metal Oxide Interfaces on MOF‐Derived 3D Carbon Architecture for Small‐Molecule Biosensing

open access: yesAdvanced Materials Interfaces, EarlyView.
MOFs awaken graphene. MOF‐assisted ultrafast laser writing patterns porous laser‐induced graphene with CuO‐active nanodomains, creating an aptamer‐ready interface for small‐molecule capture. Coupled to an extended‐gate FET, the hybrid converts subtle biochemical binding into a clear electrical signal for resilient cortisol sensing in aqueous media ...
