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 ...

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

Advanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

INSTABILITIES DUE TO RUNAWAY ELECTRONS

Acta Physica Sinica, 1980
In this paper, the effect of acceleration of runaway electrons on the microscopic instabilities is discussed. The result shows that the mechanism of instabilities is no longer a simple wave-particle resonant effect. When the resonant velocity is far away from the boundaries of the velocity region of runaway electrons, the growth rate is not ...

Ferrous Pyrophosphate Hollow Nanorods Enable Lithium Metal Batteries Under Low Negative/Positive Capacity Ratios

Advanced Materials, EarlyView.
N‐doped carbon‐coated ferrous pyrophosphate (Fe2P2O7@NC) hollow nanorods are rationally synthesized through a self‐template method. The Fe2P2O7@NC hollow nanorods facilitate uniform Li deposition as a Li host by generating LiF on the electrode/electrolyte interface, and form Li2O in the bulk phase of the electrode.
