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 ...

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 ...

Lateral energy band profile modulation in tunnel field effect transistors based on gate structure engineering

AIP Advances, 2012
Choosing novel materials and structures is important for enhancing the on-state current in tunnel field-effect transistors (TFETs). In this paper, we reveal that the on-state performance of TFETs is mainly determined by the energy band profile of the ...

Dual‐Gate Anti‐Ambipolar Transistor with Van der Waals ReS2/WSe2 Heterojunction for Reconfigurable Logic Operations

Advanced Electronic Materials, 2023
A dual‐gate anti‐ambipolar transistor (AAT) with a two‐dimensional ReS2 and WSe2 heterojunction is developed. The characteristic Λ‐shaped transfer curves yielded by the bottom‐gate voltage are effectively controlled by the top‐gate voltage.
