Processing of organic electrochemical transistors

MRS Communications
Abstract Since the advent of Organic Electrochemical Transistors (OECTs) back in the 80s, research focus has shifted from understanding the working mechanism and expanding the materials library to finding new applications and building larger integrated circuits.

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Oxygen and light sensitive field-effect transistors based on ZnO nanoparticles attached to individual double-wall carbon nanotubes

, 2012
The attachment of semiconducting nanoparticles to carbon nanotubes is one of the most challenging subjects in nanotechnology. Successful high coverage attachment and control over the charge transfer mechanism and photo-current generation opens a wide ...

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Electrolyte-gated organic field-effect transistors (EGOFETs) as complementary tools to electrochemistry for the study of surface processes

Electrochemistry Communications, 2019
We demonstrate that electrolyte-gated organic field-effect transistors (EGOFETs) can detect extremely minute modifications in the composition of the electrochemical double layers forming at the channel/electrolyte and gate/electrolyte interfaces, thus ...

Photo‐Patternable PEDOT:PSS for High Performance Organic Electrochemical Transistors

Advanced Materials, EarlyView.
Organic mixed ionic‐electronic conductors, such as PEDOT:PSS, are a special class of material capable of dual conductivity, making them a perfect choice to bridge biology and man‐made technology. PEDOT:PSS can be photo‐patterned by blending it with a photo‐sensitive interpenetrating network.

Ionic-liquid-gating setup for stable measurements and reduced electronic inhomogeneity at low temperatures

, 2018
The ionic-liquid-gating technique can be applied to the search for novel physical phenomena at low temperatures because of its wide controllability of the charge carrier density. Ionic-liquid gated field-effect transistors are often fragile upon cooling,

Correlated Charge Transport in an Organic Coulomb Glass

Advanced Materials, EarlyView.
ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of
