High Mobility (>200 cm2 V−1 s−1) Transparent Top Gate IGZO TFTs with Oxidized Metal Gate Insulator for Enhanced Conductivity

Advanced Electronic Materials, EarlyView.
We demonstrate a top gate Nb capping TFT architecture that induces controlled oxygen out‐diffusion from the IGZO channel. This mechanism generates shallow donor states and enhances electron delocalization, enabling extended percolation pathways. The resulting thin‐film transistors exhibit high mobility, suppressed leakage currents, and strong optical ...

Precisely Controlled Electrochemical Phosphonylation: Tailoring π‐Conjugated Polymer Properties for High‐Performance Organic Electrochemical Transistors

Angewandte Chemie, EarlyView.
The electrochemical C–H phosphonylation enabled precise control over the degree of functionalization (DOF). Systematic tuning of DOF (0.06–0.16) led to improved µC*, transconductance, and time constant values. This finding demonstrates that moderate functionalization enhances organic electrochemical transistor (OECT) performance, opening new avenues ...
