Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

Electrochemical rectifying device based on polymer thin films

Қарағанды университетінің хабаршысы. Физика сериясы
In this work we study the rectifying behavior of organic electrochemical transistors (OECTs). Despite OECT devices are symmetric devices they display asymmetrical output IV curves at negative and positive drain bias sweep.

Organic electrochemical transistor incorporating an ionogel as solid state electrolyte for lactate sensing [PDF]

, 2012
Room temperature Ionic liquids (RTILs) have evolved as a new type of solvent for biocatalysis, mainly due to their unique and tunable physical properties.[1] In addition, within the family of organic semiconductor-based sensors, organic electrochemical ...

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 ...

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

Channel length effects on the performance of vOECTs

Materials Research Express
Channel length ( L ), the most important parameter of various transistors, determines the transistor performance and integration density. Emerging vertical organic electrochemical transistors (vOECTs), easily enabling L of less than 100 nm, show ...

Synthesis of thin-film black phosphorus on a flexible substrate

, 2015
We report a scalable approach to synthesize a large-area (up to 4 mm) thin black phosphorus (BP) film on a flexible substrate. We first deposited a red phosphorus (RP) thin-film on a flexible polyester substrate, followed by its conversion to BP in a ...

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.
