Magnetic Droplet Manipulation on Open Surfaces

open access: yesAdvanced Materials Technologies, EarlyView.
Recent advances in the manipulation of magnetic droplets demonstrate various manipulations on open surfaces, including transport, splitting, merging, and force‐controlled motion, enabled by magnetic particles and external fields. ABSTRACT Manipulation of liquids on a smaller scale enables applications in various fields, particularly diagnostics and ...

Multi‐Dielectric Metasurfaces for Ultrabright, Tunable Structural Color and Reconfigurable Optical Filtering with Extraordinarily Large Color Span

open access: yesAdvanced Optical Materials, EarlyView.
Structural color generation is an emerging field for digital display and printing applications. This report presents a novel truncated‐cone design and the first use of GaP sandwiched between two layers of TiO2, demonstrating ultra‐bright, tunable colors with a record color gamut.

Multi‐Mode Deep Strong Coupling in a Multi Quantum Well Fabry–Perot Cavity

open access: yesAdvanced Optical Materials, EarlyView.
Multi‐mode deep‐strong coupling is demonstrated in a 166‐well heterostructure that acts as a Fabry–Perot cavity. Even cavity modes couple strongly to the cyclotron resonance, producing large vacuum Rabi splittings and a rich polaritonic spectrum captured by a full Hopfield model.

Tailoring Electric and Magnetic Dipole Emission of Er3+ Ions via Toroidal Dipole Resonance of Si Nanodisk Hexagonal Array

open access: yesAdvanced Optical Materials, EarlyView.
Hexagonal arrays of silicon nanodisks are proposed to control 1.5 µm emission of Er3+ ions. Toroidal dipole resonance of the nanodisk array generates accessible magnetic hot spots at the surface, leading to enhanced and highly directional magnetic dipole emission along the surface‐normal direction via the magnetic Purcell effect.

Strontium Charge‐Generation Assistant Layer for High‐Performance Tandem Organic Light Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
An ultrathin Sr interlayer is introduced as a charge‐generation assist layer to overcome the electron‐injection barrier in deep‐LUMO charge‐generation layers (CGLs) of tandem OLEDs. The Sr layer facilitates trap‐assisted tunneling and lowers the effective injection barrier, enabling improved charge balance and yielding tandem OLEDs with doubled ...

Probing Near‐Field EM Fluctuations in Superparamagnetic CoFeB With NV Quantum Dephasometry

open access: yesAdvanced Optical Materials, EarlyView.
We non‐invasively investigate the superparamagnetic spin dynamics of a 1.1 nm CoFeB layer by probing its near‐field EM fluctuations using NV centers‐based quantum dephasometry. Our findings are further supported by theoretical modeling and SQUID‐based magnetization characterization. These results provide critical insight into the magnetization dynamics

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
