Hysteresis Dynamics in Double-Gated n-Type WSe₂ FETs With High-k Top Gate Dielectric

IEEE Journal of the Electron Devices Society, 2019
We propose double-gated n-type WSe2 FETs with low leakage, low hysteresis top gate high-k dielectric stack. The top gate dielectric layer is deposited by HfO2 ALD on an Al2O3 seed layer obtained from the evaporation and oxidation by air exposure of a 1.5

An Overlooked Transport Mechanism in Organic Mixed Conductors

Advanced Functional Materials, EarlyView.
Electrical transport in organic mixed ionic‐electronic conductors is commonly described by ionic and electronic conduction. Here, eumelanin reveals that polarization‐assisted displacement currents constitute an additional transport component that coexists with conductive transport.

Biocompatible Conjugated Electrospinning Nanofibrous Membrane With Self‐Powered Piezoelectric Capacity for Accelerated Wound Healing

Advanced Healthcare Materials, EarlyView.
A self‐powered PCL/gelatin‐PVDF‐TrFE/MXene conjugated electrospun membrane integrates biocompatibility with enhanced piezoelectric responsiveness. Mechanical deformation is converted into localized electrical signals that stimulate wound‐repair cells proliferation and migration, promote angiogenesis and tissue remodeling, and accelerate full‐thickness ...

Hysteresis in Unemployment: Evidence from Norwegian Counties [PDF]

The paper tests hysteresis effects in unemployment using aggregate and panel data for Norway. While tests using aggregate or county— specific time series do not reject the null of unit root hysteresis, the panel tests firmly reject the null.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

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 ...
