Doping‐Free Polymer Nanoparticle Engineering of n‐Type Organic Mixed Ion–Electron Conductors for Enhancement‐Mode Organic Electrochemical Transistors

Macromolecular Rapid Communications, EarlyView.
We report a nanoparticle formulation strategy for the ladder polymer BBL that enables undoped enhancement‐mode OECTs. Controlled reprecipitation with DBSA yields stable nanoparticles, and spray‐coating forms dense, well‐connected films. The resulting devices exhibit strongly enhanced electrochemical response and transconductance, establishing a ...

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...
