THE AMBIPOLAR ELECTRIC FIELD AND THE AMBIPOLAR DIFFUSION IN A STOCHASTIC MAGNETIC FIELD
Acta Physica Sinica, 1981 It is shown that the transport of the plasma immersed in a stochastic magnetic field (s.m.f.) must lead to the producing of an ambipolar electric field. In this paper, the transition probability of charged particels in the s.m.f. was derived in the case of existing a transverse electric field.

The singular behaviour of ambipolar diffusion revealed by 1D Cartesian solutions
Astronomy & AstrophysicsContext. Ambipolar diffusion is increasingly recognised as a key process in the lower solar atmosphere. Its highly non-linear behaviour has many non-intuitive aspects. Aims.

Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion
Advanced Materials, EarlyView.This article explores charge transport in mixed ionic‐electronic conductors (MIECs) through electrochemical impedance spectroscopy and transient current analysis. Focusing on PEDOT:PSS, WO3, and n‐doped PBDF, it uncovers the impact of anomalous diffusion via fractional modeling. The study reveals key correlations that deepen understanding and guide the

Physics of Plasmas, 2019 The ambipolar electric field in a tokamak with a magnetic field ripple, in the superbanana regime of collision frequency, is studied dynamically. Gauss's law, charge conservation, and a known formula from neoclassical theory reveal the relaxation of the radial electric field to its ambipolar value, with a time constant that is nearly independent of the

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 ...
