Kinetic regulation of blended electrolytes enables long‐term state retention in organic artificial synapses

InfoMat, EarlyView.
Organic electrochemical transistor‐based artificial synapses are promising for neuromorphic computing, yet their performance is limited by poor state retention. Here, a kinetic regulation strategy is demonstrated using a blended poly(ionic liquid)/ionic liquid electrolyte.

High‐mobility p‐type Te0.65Se0.35 thin‐film transistors with self‐passivating contacts

InfoMat, EarlyView.
Te0.65Se0.35 alloy is a promising p‐type semiconductor, with problems of high contact resistance and Schottky barriers limiting its device performance, which can be solved by applying O2‐plasma treatment to form a self‐passivating TeOx layer, and this treatment achieves a hole mobility of 88.8 cm2 V−1 s−1 and a fivefold increase in on‐state current ...

Addressing transconductance-bandwidth trade-off by three-dimensional electrolyte-surrounded organic electrochemical transistors

The performance of organic electrochemical transistors (OECTs) is fundamentally constrained by a trade-off between transconductance and temporal response. While increasing channel thickness enhances its capacitance and thereby amplifies transconductance,

Ionic Liquids at the Interface With the Transition Metal Dichalcogenide MoS2: Effect of the Chemical Structure on Induced Charge Carrier Density

Small, EarlyView.
Ionic liquid gating of MoS2 channels using [EMIM][TFSI] or [EMIM][BF4] can lead to different carrier densities. [TFSI]‐based systems exhibit steeper voltage decay (compared to [BF4]‐based systems) meaning the potential drops more rapidly across the electric double layer, indicating stronger local electric fields and more efficient charge accumulation ...
