Trapped mode resonances in metalo-dielectric structures with electric asymmetry

open access: yes
The excitation of an anti-symmetric trapped mode on a symmetric resonator structure is demonstrated through numerical simulation. The electrical symmetry is broken by using different dielectric substrates leading to trapped modes being excited onto a ...

In Situ Regenerative Adduct Assisted p‐Type Doping of Organic Semiconductor

open access: yesAdvanced Materials, EarlyView.
An in situ regenerative adduct‐assisted (IRAA) doping strategy is introduced for p‐type doping of organic semiconductors. A regenerating adduct serves as the dopant, enabling highly efficient doping with a choice of counterions. The generality of this approach provides a scalable route to dope a wide range of hole‐transport materials with high thermal ...

Left handed rectangular waveguide resonator structures

open access: yes, 2005
SRRs are constructed as two square-shaped rings, each interrupted by a small gap, as shown in Fig. 1. Embedding small single split resonator elements on a dielectric substrate we obtain negative magnetic permeability for a metamaterials-based ...

Closed‐loop Recycling of Sulfide Solid Electrolytes from Spent Solid‐State Sodium Batteries

open access: yesAdvanced Materials, EarlyView.
Closed‐loop recycling of sulfide solid electrolyte via a mild dissolution–recrystallization–thermal treatment process enables efficient recovery from spent all‐solid‐state sodium batteries. The regenerated material preserves the crystal structure, local coordination, and chemical states, maintaining high ionic conductivity, reduced interfacial ...
