Polymer Sequence Design of Zwitterionic Polymer/PEDOT:PSS Blend Films for Improved Charge Transport and Stability in Organic Electrochemical Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Solution blending of zwitterionic polymers with PEDOT:PSS provides a simple route to OECT materials with enhanced threshold voltage stability in biologically relevant environments. The polymer sequence alters outer‐domain structure within the preserved PEDOT:PSS framework, thereby tuning charge transport.

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

open access: yesAdvanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

Backbone Engineering of Benzodifurandione‐Based n‐Type OMIECs With Antiambipolar Behavior

open access: yesAdvanced Electronic Materials, EarlyView.
Two novel n‐type polymeric organic mixed ionic‐electronic conductors based on an azaisatin and benzodifurandione backbone are developed to enhance aqueous electrochemical devices. This backbone modification provides organic electrochemical transistors with high ambient stability, low threshold voltages, and tunable antiambipolar behavior, opening new ...

Metal Cation Chemistry and Amorphous Structure Governing Hydrogen Tolerance in Oxide Semiconductor Channels for 3D DRAM

open access: yesAdvanced Electronic Materials, EarlyView.
Amorphous In–Sn–Ga–O channels are presented as hydrogen‐tolerant oxide semiconductors for DRAM‐relevant thermal processes. Systematic comparisons of ternary oxides separate elemental and crystallinity effects under 400–600°C H2 annealing. Sn incorporation and amorphous structure suppress thickness loss and enable field‐effect transistors to retain ...

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

open access: yesAdvanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...
